Laser Safety Precautions
The laser beam in the optical gauge is very powerful and can permanently
damage eyes not protected by laser safety glasses. To avoid exposing
yourself to hazardous radiation, you must take these precautions:
Safety Information
• Never look into the laser beam. If you must look at the beam,
view it from an angle and in the direction in which the beam is
travelling.
• The beams emitted from the Model LS8000-3 are invisible to the
unaided eye. Return the beam shutter to the closed position
when the system is not in use or during setup.
• Ensure that all direct reflections are blocked.
• Remove all rings, watches, or jewellery from your hands when
working on or near the gauge—can cause hazardous reflections.
• Never install the instrument at eye level.
• Operate the system only with people who have been instructed
in laser safety.
• Post warning signs and lights that are active when laser is
operating.

Introduction
This manual describes the installation and setup of the LaserSpeed 8000
gauge. For daily routine usage, see the LaserSpeed 8000 Operator Guide.
The Model LS8000-3 LaserSpeed® Non-contact Length and Speed gauge is
an industrial, Laser-Doppler based instrument that measures the velocity and
length of material. Due to the nature of the laser-based measurement, there is
no physical contact with the material. This eliminates the problems of wheel
wear and slippage that plague mechanical/encoder based length
measurement systems.
System Overview
The Model LS8000-3 is a stand-alone instrument that requires only 24 VDC
input power to operate. The system has a variety of industrial outputs. Also, a
variety of information including length, velocity, system operating parameters,
and setup parameters can be read and configured using the communications
interfaces.
Introduction
The LS8000-3 is permanently calibrated to a NIST traceable standard at the
factory. Aside from periodic cleaning of the optical window, the LS8000-3
does not require maintenance.
See the Specifications section at the end of this manual.
Principle of Operation
LaserSpeed utilizes dual-beam interferometer technology to provide accurate
velocity readings. The measured velocity is integrated over time to measure
the length of moving objects. The opto-electronic portion of the LS8000-3
generates a laser beam that is split and then crossed in space. The two
crossing beams interact, producing a fringe pattern that is orthogonal to the
plane of the two beams.
Light is scattered when material passes through the measurement region. This
scattered light is collected by the gauge and converted to electrical signals.
The frequency of the electrical signal contains information with regards to the
velocity of the material. The signal processor converts the electrical signals to
frequency information that is directly proportional to the velocity of the material
moving through the laser beams. The signal processor converts the frequency
information into velocity information and updates user outputs. In order to
determine if there is an object in the measurement area, the gauge measures
the amount of reflected laser light.

Mounting Distance
When the material is within the depth of field, the gauge makes accurate
measurements. Since the best signal comes from the center of the depth of
field, the center is the source of the best measurements. This is because the
two laser beams totally overlap at the center of the beam crossings and all of
the laser power is used to form fringes.
At the edges of the depth of field, however, some beam-crossing areas
overlap and some do not. The areas that overlap form fringes and thus yield
useful Doppler signals; the areas that do not overlap do not form fringes;
rather, they produce only noise with no Doppler signals. Any measurements
made outside the depth of field may not be reliable.
Laser Safety
When mounting of the gauge, ensure that the laser beams are blocked by
machinery or beam blocks when material is not present in the measurement
area.
Installing the System
Environmental Conditions
Ambient Temperature
All LaserSpeed gauges have a built-in cooling system for applications in which
ambient temperatures exceed 45ºC.
Cooling fluids can be routed through the gauge using the 1/8-inch NPT fittings
(1/4" NPT on LS8000E and LS8000X) on the back of the gauge. Typical flow
rates of 1.5 litres/minute for water and 50 liters/minute for air are sufficient.
There is minimal pressure drop through the gauge, so supply pressure can be
very low.
Ensure that the water temperature is above the condensation temperature or
dew point, to prevent condensation from collecting on the front window of the
gauge. If water condenses on the optical window, the laser beams could be
blocked, resulting in reduced performance or loss of function.
Coolant
In applications with coolants on the material, an air jet may be required to
remove the coolant from the measurement area. Since the speed of the
coolant is generally different from that of the material, erroneous
measurements could result. When incorporating an air jet, be sure to blow the
coolant from the measurement volume at 90° from the material’s motion. If the

coolant is blown off in the same direction the material is moving, the air
velocity can add or subtract from the material’s velocity; this too may cause
erroneous measurements.
Air Wipe / Quick Change Window
To prevent dust, dirt, and moisture from accumulating on the optical window
the gauge can be fitted with an Air Wipe/Quick Change Window. Clean,

pressure over the window to keep it clean. The window can be removed for
easy cleaning. A clean, soft cloth should be used to clean the window. If an
abrasive cloth is used, the optical coating may be damaged, leading to poor
measurements. When replacing the window, put a small amount of vacuum
grease on the O-Ring.
section for details) is blown at low
Installing the System
For measurements and details about removing the Air Wipe/Quick Change
Window, see Appendix A
.
Steam & Mist
Steam or mist is sometimes present in some applications. The air-wipe is not
designed to clear steam or mist between the gauge and material, but only to
keep contaminants from depositing on the optics window. Another means of
removing steam or mist may need to be used. The steam or mist may be light
enough to allow the laser beams to pass through without interference. If this is
not true, a fan may be used to clear out the steam or mist between the gauge
and housing. If a fan is not adequate or practical, an “air purge” can be
installed to clear the beam path. Contact your Beta LaserMike representative

for more details. When mounting the gauge, be aware of the environment in
which the gauge is operating. Steam, mist, coolant on the material, ambient
temperature, scale and slag may all affect the performance of the gauge.
These environmental conditions may need to be modified as mentioned above
in order to maximize the performance of the gauge.
Mounting Location
When mounting the gauge over the
material, be sure the gauge is not
directly over a roller or some other
device. If the laser beam from the gauge
strikes an object, it may detect a false
Material Present. In this case, the gauge
will not be able to detect when the
actual material is not in the
measurement volume.

Twinner Lines
When mounting the gauge on a twinner line, the gauge should be positioned
far enough from the twinner that the twist is set. If the gauge is placed close to
the twinner, it may not be able to measure due to excessive vibration and the
spin imparted on the wire due to the twisting motion. Moving the gauge down
the line farther from the twinner may improve the gauge's ability to make
measurements.

LaserSpeed 8000-3 Instruction Handbook
Aligning the Gauge
Once the gauge is mounted at the proper standoff distance, the critical
alignment angles need to be checked. To obtain accurate results, the LS80003 must be mounted so the surface being measured is perpendicular to the
optical axis. The best method to ensure this is to place a level alongside the
gauge. The material being measured should be parallel to the front face of the
gauge and the material motion should be parallel to the base of the gauge.
The velocity measurement, which is made in the plane of the two laser beams,
is the rate at which the material passes the fringes of the beams. When the
motion of the material is perpendicular to the fringes, the velocity
measurement is considered calibrated. If the fringes are at an angle to the
motion of the material (angular rotation), measurement errors occur. The
measured velocity equals the actual velocity multiplied by the cosine of the
angle by which the alignment deviates from the direction of material
movement.
Installing the System
Three types of misalignment are possible. Two of the three are responsible for
measurement errors: rotation about the optical axis and tilt in the plane of the
beams. The errors are proportional to the sine of the misalignment angle.
Misalignment will always make the gauge measure velocities and lengths that
are too low.

Connecting to Outputs
On the LS8000-3 model, the outputs of the gauge are contained on the 9-pin
and 25-pin D-sub connectors, and the M12 D-Coded Ethernet connector. On
the LS8000-3E and LS8000-3X, all outputs are contained on a 39-pin circular
connector. Their pin values are shown in the following tables. Each signal is
explained in detail in the Interfacing with the LS8000-3 section.
Note: In order for the LS8000-3 to be operational, pins 16 and 17 must
be connected to signal ground. These signals operate the internal
laser shutter and the laser interlock. When these connections are
open, the laser will not turn on and the shutter will not open. You
must provide the correct signals to operate the gauge.

Maximizing Performance
The system is now at the point where it can be powered on and the laser
activated so beams are emitted from the front of the gauge. Be sure that the
laser interlock and shutter control circuits are functioning properly.
When Pin 16 is connected to GND (Pin 11, 19, or 21), the laser
becomes operational.
When Pin 17 is connected to GND (Pin 11, 19, or 21), the shutter will
open.
Check the key switch to verify the laser power can be controlled.
Warning: Avoid exposure to the beam. Never look directly into the laser
beams, even when wearing protective eyewear. Eye damage
could result.
Installing the System
Note: There may be some delay time between when the system is powered
on, and when the laser comes on. There is a 7 second delay after
power is applied to the laser (key switch on, laser interlock closed)
before the laser turns on. The laser will also not turn on until the
laser temperature controller stabilizes. This may take a few minutes
after power is initially applied. The standoff distance can be verified
by using a business card or sheet of white paper. Both beams can
be viewed and the area where the beams overlap is the active
measurement region. The location where the overlap of the beams is
smallest is the center of the measurement region. This location
corresponds to the standoff distance and is where the beams should
intersect the product.
The configuration and setup of the gauge can be verified and/or changed
using the supplied LaserTrak Software or directly using the serial commands
listed in the Communication Protocol
approaches requires a computer with an RS-232 serial port connected to pins
1 and 2 of the 25-pin D-sub connector, or an RS-422 serial port connected to
pins 1-4 of the 9-pin D-sub connector.
Once proper communication is established (see the See the LaserTrak
Software section for help), it is recommended to check the Quality Factor (QF).
QF can be checked using LaserTrak, and viewing the chart recorder screen. If
it is below 15, try to move the product or the gauge slightly (adjust the
standoff) and look for improvements in QF. Once QF is maximized, change
the line speed and look for a corresponding velocity change on the chart
recorder.
section. Utilizing either one of these
Part No. 93463 / Drawing No. 0921-01561 Page 31 of 221 Revision A (Sep 2007)
LaserSpeed 8000-3 Instruction Handbook
Alternatively, the analog port can be configured to output QF on a 0–1 V scale.
The QF can then be monitored by connecting a panel meter to the analog
output and displaying the voltage. A third method of monitoring the Quality
Factor is to reassign one of the pulse outputs to output the Quality Factor as a
frequency output.
To ensure quality measurements, the laser beams must maintain “contact”
with the product. If the product exhibits large movements during operation, it
should be stabilized with external roller guides. Beta LaserMike offers optional
product guides. Contact your local Beta LaserMike sales representative or the
factory for additional information.
Material Present Adjustment
The intensity of the light reflected from the measurement area can be used to
determine whether material is in the measurement zone or not. To
compensate for varying reflectivity of different materials, it is often necessary
to adjust the threshold of the light detection circuit. This adjustment can be
made with a serial command or by using the LaserTrak software.
Installing the System
Material Present Dropout Time Selection
If you are taking measurements and the Material Present signal is lost for less
than the selected Material Present dropout time, the loss is considered to be a
momentary loss of signal and is ignored. If the signal is lost for longer than the
selected Material Present dropout time, it is considered the end of the material.
This function is very useful when making length measurements on poor
reflecting material.
Validation Time Limit Selection
The validation time limit is used to start making length calculations. Two
conditions are necessary to start a length measurement: Material Present and
valid velocity data. When material enters the measurement volume, the
system determines the time between the Material Present signal and the first
valid data. If the time is less than or equal to the validation time limit
(selectable via LaserTrak or ‘G’ command), then the start-up length-correction
is calculated and a length measurement is initialized. If the time between the
Material Present signal and the first valid velocity data is longer than the
validation limit, then the length calculation is aborted and an error or fault is
sent. This error is sent by setting the length output (either in continuous output
mode or Final Length Mode) to all 9’s.
Part No. 93463 / Drawing No. 0921-01561 Page 32 of 221 Revision A (Sep 2007)
LaserSpeed 8000-3 Instruction Handbook
Starting/Ending Length Correction
The Validation Time Limit feature is used because the Material Present signal
tells the gauge that material is indeed moving through the measurement zone.
If valid velocity measurements cannot be made, then a small amount of length
will not be accumulated which, in turn, will cause a length error. This may or
may not be a problem, depending on the velocity of the material when it
passes through the measurement volume during this time. The start-up
length-correction is executed to obtain a more accurate length reading. Each
measurement update is divided into small subintervals. When the Material
Present signal is received within an update period, the time it was received is
recorded with a subinterval clock. The length is calculated by using valid
velocity and integrating over the time measured with the subinterval clock. For
example, if the material speed is 10 meters per minute and material enters the
measurement volume in the middle of the 1-millisecond update period, the
subinterval time of 0.5ms is used to calculate length rather than the 1millisecond period. In this case, a 0.083 mm correction would be made. The
same type of correction is made when the material leaves the measurement
volume.

The 25-pin interface port contains pins which deliver the quadrature pulse
outputs, RS-232 serial communications, safety interlock signals, and the 24 V
supply required to power the gauge. Several inputs are available for operation
of the instrument. The connector is a standard 25-Pin male D-Sub connector.
The connector is shown below looking at the gauge's rear panel with the
gauge base plate down.

High Speed Pulse Output (Pins 3, 5, 7, 9)
This quadrature pulse output is a high-speed RS-422 drive output with an
output rate up to 5MHz. This pulse output uses an RS-422 transceiver to
generate its output signals, and so should be connected to an RS-422
transceiver on the receiving end. These pulse outputs can be connected to a
PLC high speed counter card for fine length resolution and high-speed velocity
measurement.
If you need to convert the differential RS-422 level pulse signals to TTL levels,

outputs are opto-isolated signals with a voltage level determined by the
voltage supplied on Pin 20 (referenced to User-Ground (pin 11, 19, or 21.) An
isolated TTL level signal (3.7-5V) will be supplied if no external voltage is
connected. The output drivers can handle from 5 to 24 VDC. The external
supply requirements are 5–24 volts DC at 300 mA.
The Low Speed Pulse Output can be reconfigured to output several different
status outputs using the Low Speed Pulse Output Configuration setting.
See the Configuration Settings

Differential vs. Single Ended Pulse Outputs
IN input. The pulse
The LS8000-3 Pulse Outputs are available as both differential and singleended outputs. Using a counter with differential inputs will provide the best
noise immunity, so Beta LaserMike recommends that the outputs are used in
this configuration.
Unfortunately, many counters do not have differential inputs. The pulse
outputs can be used as single ended inputs by connecting Phase A True and
Phase B True to the counter inputs, and connecting the counter ground to
User Ground (pins 11, 19, 21). Leave the Phase A False and Phase B False
outputs unconnected when connecting for single ended output. If extra counts
occur when the line is not moving, or when the LS8000-3 is powered down,
then noise is getting into the cable and triggering the counter. In this case,
using a conversion circuit to convert from differential to single ended outputs
may correct the problem.

LaserSpeed 8000-3 Instruction Handbook
Interfacing with the LS8000-3
Because the opto-isolator in the circuit has a relatively slow response time
compared with the LaserSpeed's maximum pulse output frequency, when
using this circuit, keep the LaserSpeed's pulse output frequency below 20kHz.
Quadrature Output Phase Relationships
The phase relationship of the quadrature outputs is determined by the
direction of the measured velocity. If the velocity is a positive number, Phase
A rising edge will lead Phase B rising edge, and if the velocity is negative
Phase B will lead Phase A rising edge. For more information on the direction
input, see Operational Inputs.

Typical Full Quadrature Pulse Train with Negative Velocity
Note: If excessive or erratic counts are noticed, the main cause is usually
improper termination of the pulse signals. It is recommended you look at the
signals (while connected to the external counter) with an oscilloscope to
determine if excessive ringing or rounding of the pulse train is present. A 100Ω
resistor can be used between true and false signals for differential
output.

Quadrature Outputs at Extremely Low Pulse Frequencies
Note: This section only applies to the pulse outputs—the length and speed
available over the RS-232, RS-422, and Ethernet ports are not affected.
The LS8000-3 uses a DDS (Direct Digital Synthesis) circuit to generate the
quadrature outputs. Due to the nature of DDS technology, the frequency
output is not continuously variable, but occurs in steps of about 0.015Hz.
Normally, relative to the output frequency, this step size is so small that it is
impossible to measure. However, if both a very low speed is measured, and a
very low pulse
resolution is used, the
pulse output
frequency will be

The error decreases very rapidly as the frequency increases, becoming
insignificant at pulse output frequencies higher than 15Hz. For this reason, the
pulse output resolution should be set such that the minimum production line
speed produces a pulse output frequency higher than 15Hz.
The following equations can be used to calculate the minimum pulse output
resolution.

Material Present Input (Pin 10)
This is an optically isolated input that can be used to externally control the

connected to the User V

Optically Isolated Input Schematic
The LS8000-3 can internally sense Material Present, but there are situations
where it is advantageous to determine this externally. This input can also be
used to start and stop length measurements. This input is typically used in the
following situations:
Continuous Processes such as Cold Mills, where there is always metal
in front of the gauge. The input can be used both to start/stop length
measurements, and to prevent the LS8000-3 from sending speed
data/pulses to the PLC while the line is stopped. The LS8000-3 can be
configured to clear the measured velocity to 0 and hold the pulse
outputs when the Material Present input is in the "Material Not Present"
state.
Discrete Part Length applications can take advantage of this input to
increase the precision of length measurements. Two material
detection gauges (such as optical make/break gauges) can be
mounted on either side of the LS8000-3
This input is functional only when the Material Present Input Mode has been
set to External Mode. Activating this input causes a new measurement to
begin. This resets the current length, and resumes counting at 0.
Deactivating this input causes the current measurement to end, which causes
the length to hold at the current value. If in Final Length Mode, the final length
will be output on the RS-232/RS-422/Ethernet port. The functionality of this
input varies with the Material Present Input Mode. The Material Present Input
Mode is configurable through LaserTrak, or by using the “S” serial command.

LaserSpeed 8000-3 Instruction Handbook
Interfacing with the LS8000-3
Example 1:
You are using an external make/break optical switch to begin and end the
measurement. The optical gauge has a smaller spot size than the LS8000-3,
so it will more exactly detect the edge of the product. When the part enters the
measurement area the switch outputs a Low (0V) signal, and when there is a
part in the measurement area, the switch outputs a High (24V) signal. So,
when the part enters the measurement area, a LowHigh transition occurs,
and when the part exits the measurement area, a HighLow transition occurs.
This configuration requires that you set the Material Present Input Mode to 2
(External/Active High). When the part enters the measurement area
(LowHigh) a measurement begins, and when the part exits the
measurement area (HighLow) the measurement ends. If the LS8000-3 is in
Final Length Mode, the elapsed length will be transmitted over the serial port
when the part exits the measurement area.

Connecting Material Present Switches
This section shows how to connect a commonly used Material Present
detector.
Single Switch Configuration
The D10 is a make/break optical switch. When connecting one optical switch,
it should be aligned with the LS8000-3's measurement spot. This
configuration can be used in order to more precisely detect the edge of the
material. The fiber optic elements are much smaller than the LS8000-3 spot
size, so repeatability is improved by more consistent edge detection.

switch should be configured for Super High Speed (SHS) mode in order to
minimize latency.

LaserSpeed 8000-3 Instruction Handbook
Interfacing with the LS8000-3
When the product enters the measurement area and triggers the switch, the
Material Present signal should activate. This causes the LS8000-3 to start
counting length at 0. When the product leaves the measurement area and the
Material Present signal deactivates, the LS8000-3 will calculate the final length
and the measurement is complete. If in Final Length mode, the LS8000-3 will
transmit the Final Length over the serial/Ethernet ports.
Dual Switch Configuration
Two optical switches can be connected in parallel in order to further increase
the precision of part-length measurements. This configuration is typically used
on discrete part measurements that are long and have a very tight length
specification. The LS8000-3 repeatability specification is ±0.02% of the
measured length.
Example:
A cut-to-length application has a product that varies from 14 ft. (4.27m) to 16
ft. (4.88m) in length, and has a tolerance of ±1/8 inch (±0.125in./±3.2 mm.)
The LS8000-3 repeatability specification for a 16 ft. length is a little more than
±1/32 inch (±0.97mm.) While this is better than the length specification, the
measurement variation is only about ¼ the length specification. Ideally, a
measurement instrument's variation should be 10X smaller than the
specification it is required to measure.
In order to improve repeatability, the LS8000-3's measured length can be
reduced by using two optical switches to gate the LS8000-3's measurements.
The LS8000-3 will only measure while the product blocks both optical
switches. In this case, since the minimum part length is 14 ft (4.27m), the
switches could be placed 13 ft (3.96m) apart. This will reduce the length that
the LS8000-3 measures to between 1 and 3 feet. The repeatability will then
be ±0.02% of 1-3ft instead of ±0.02% of 12-16ft. The new repeatability would
then be ±0.0072 inch (0.18mm.) Because the distance between the two
switches is fixed, this value can be added to each length measurement that
the LS8000-3 produces using the Length Reset Value Setting ($R
configuration setting.)
The optical switches should be arranged and wired as shown below:

passes that point again, the Index Pulse will not be repeated.
The Index Pulse is asserted for a configurable amount of time. This time can
be configured by changing the Index Pulse Length setting. See the
Configuration Settings
section for details.
Example:
Index Pulse Length = 100ms
Index Pulse Interval = 10m
Index Pulse Output Example
The Index Pulse Output can be reconfigured to output several different status
outputs using the Auxiliary Digital Output Configuration setting. See the
Configuration Settings

DB9 Connector
The 9-pin interface port contains the RS-422 interface pins for high speed,
long distance communication with the LS8000-3, the Analog Output, and the
Measurement Synchronization Input pins. The connector is a standard 9-Pin
male D-Sub connector. It is shown below looking at the gauge's rear panel
with the gauge baseplate down.

These pins comprise the RS-422 interface port. The RS-422 communications
port can be used at speeds up to 230kBaud over long distances. The
transmission cable should be a shielded, twisted pair cable. RS-422 uses
balanced pairs for both transmission and reception, so the +/- lines for the
Transmit and Receive pairs should be paired as shown. To minimize
reflections, the transmit lines from the gauge should be terminated with a
resistor matching the characteristic impedance of the cable (100Ω) as shown
below. The cable shield or drain wire should be attached to the chassis
ground at both ends of the cable. At the gauge end, a DB9 connector with a
metal backshell should be used, and the cable shield should be terminated to
the backshell. The cable jacket should be suitable for the environment to
which the cable will be exposed.

Analog speed data can be obtained in a 0–2 V format. An optional selectable
voltage/current output module which will convert the 0–2 V signal supplied by
the gauge to all of the common voltage/current levels is available. The analog
output indicates speed but not direction.
There are two configuration settings that affect the operation of the analog
output. The Analog Zero Scale Velocity sets the speed where the analog
output reaches 0V. The Analog Full Scale Velocity sets the speed where the
analog output reaches 2V. At speeds between these two settings, the analog
output increases linearly as the speed increases from the Analog Zero Scale
Velocity to the Analog Full Scale Velocity.
Example: If the Analog Zero Scale Velocity were set to 30 m/min, and the
Analog Full Scale Velocity were set to 100 m/min, the analog output would
behave as shown in the following figure.

the Full Scale Velocity to zero using a serial

Measurement Synchronization Input (Pins 8-9)
In many AGC applications, particularly mass flow control, it is desirable to
synchronize the sampling periods of all gauges in the system. This is done by
connecting an LS8000-3 I/O Module to each LS8000-3 in the system (for

elongation), or by connecting the LS8000-3 gauges together in a daisy-chain
configuration (for synchronization only.)
Using the LS8000-3 I/O Module (one I/O Module per LS8000-3) easily allows
multi-channel synchronization and elongation measurement. The I/O Module
has rear panel Sync connectors that can be connected to other I/O Modules
for synchronization. For details about synchronizing multiple gauges using the
LS8000-3 I/O Module, refer to the LS8000-3 I/O Module Instruction Handbook.
For details about how to connect multiple LaserSpeed gauges together for
synchronization, see the Gauge-Gauge Synchronization
When two or more systems are synchronized, the speed data is synchronous,
although there will be minor variations in the actual output times from one I/O
Module to the next. This means that all processors sample over exactly the
same time period, but due to minute differences in internal processing times,
the output from each processor may arrive a few microseconds earlier or later
than the outputs of the other I/O Modules.

Heavy Industrial Cables
LaserSpeed 8000-3 Instruction Handbook
Interfacing with the LS8000-3
LaserSpeed heavy industrial cables are designed for use in heavy industrial
environments where high temperatures and heavy coolant spray are
encountered. They have an extremely durable outer jacket, and are
impervious to industrial lubricants, coolants, and solvents.
Never pull the cable by the connector. Always attach the pulling cable to
the cable itself. Pulling the cable by the connector may damage the connector
pins. The circular connector has a protective end cap that should be screwed
over the cable pins when pulling through conduit, or any time the cable is
disconnected from the LS8000.
The cable must be screwed onto the LS8000-3 connector until it fully seated—
the yellow stripe on the LS8000-3 connector is not visible when the cable is
fully tightened.

connecting the gauge to a recirculating heater/chiller, but can also be
accomplished by using the gauge's thermostat output. LaserSpeed gauges
monitor their internal temperatures, and can provide an output indicating when
cooling/heating is required. This output can be connected to a valve or a PLC

specified length interval, and the Length Thresholds can be configured to
trigger at preset lengths before the Index Pulse triggers. The Length
Threshold outputs remain high until the Index Pulse triggers and resets. The
index pulse automatically resets the Length Threshold outputs—no external
wiring is required.
Another way to reset these outputs is to set the Index Pulse Setting to a high
value and reset the threshold outputs by asserting the Length Reset Input.
The Length Thresholds are available as an alternate output function of the
User Scaleable Pulse Output.
Example:
Setting Value
Index Pulse Setting 100 m
Index Pulse Length 100 ms
Length Threshold A 90 m
Length Threshold B 80 m

Gauge-Gauge Synchronization
LaserSpeed LS9000 and LS8000 gauges can be synchronized so that their
sampling periods are synchronized, and so they update their outputs at the
same time.
The simplest method for synchronizing gauges is to connect each gauge to a
LaserSpeed I/O module and connect the I/O Modules' synchronization
connects together. The I/O Modules will automatically synchronize the gauges
and calculate elongation, which can be output in a variety of different ways.
Another method for synchronization is to reconfigure the gauges' High Speed
Pulse Output ports and connect the gauges together in a daisy-chain
configuration. The gauges will synchronize to each other, but will not calculate
elongation. If an elongation calculation is required, the RS232, RS422, or
Ethernet output data from each gauge must be collected and calculated in an
external PLC or computer.
To configure the High Speed Pulse Output to output the synchronization
signal, use LaserTrak to set the High Speed Pulse Config option "A=Pulse
Phase A, B=Sync Out". This will replace the pulse output phase B with the
synchronization output, and will leave Phase A available for connection to a
counter.

LaserTrak Software
LaserTrak® is a Windows®-based software program, which allows you to
acquire and display the Length, Velocity, Quality Factor, and Gauge Status in
real time. The LaserTrak software configures the respective gauge’s operating
parameters, displays data, and collects data, which can be stored to a
computer hard drive. This LaserSpeed series of non contact speed and length
gauges provide a set of versatile tools that are applicable for a wide variety of
process measurement schemes. LaserTrak allows you to take full advantage
of this versatility in a straightforward, easy to understand manner.
There are several features available with the LaserTrak software. LaserTrak
mimics a chart recorder output on the screen and monitor the speed, length
and Quality Factor in real time and presents a time history depiction of the
data. LaserTrak can acquire and store data, and load and display stored data
from a previously acquired data file.
LaserTrak Software
LaserTrak for Windows
Note: LaserTrak Version 4.0 or later must be used with the LS8000 gauge.

Note: Make sure that the LaserSpeed gauge is connected to the computer
via RS232, RS422 or Ethernet before starting the LaserTrak
software. The first thing the LaserTrak software does is establish
communication between the LaserSpeed gauge and the computer. If
no gauge is connected, communication will not be established and
you will see the following screen.
If you get the Gauge Not Found message, you can still run LaserTrak by
recalling and displaying stored data.

Length (m) – the length on the LaserSpeed gauge’s length counter. The
length is accumulation from the last time the gauge was reset.
Length is displayed in the units set during gauge
Configuration.
Vel (m/min) – the instantaneous speed measured by the LaserSpeed
gauge. The speed is displayed in the units set during gauge
Configuration.
QF- the instantaneous Quality Factor measured by the LaserSpeed
gauge. QF is displayed as a number between 0 and 15,
where 15 represents the best and 0 represents no
measurements being made.
Average QF- the average of all the QF readings since the LaserTrak
software started acquiring data from the gauge. This value is
