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.

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

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.

fusing (3A, 125 V) on the 24 VDC supply line. This fuse is not user
serviceable.
Installing the System
The following figure shows the correct installation of the recommended switch
(C&K Components part number YM06132C205NQ). If another type of key
switch is used, it should be verified that the key is removable only in the “Laser
Off” position.

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.
