1 GENERAL DESCRIPTION

Portable infrared thermometers measure surface temperature without touching the surface. They collect the infrared
energy radiated by a target and compute its surface temperature.

OMEGA OSP Series

enable the monitoring of operating temperatures of mechanical and electrical plants or production equipment without
removing the equipment from the service.
Any temperature variation noticeable in whatever kind of system device should show critical overheating conditions
which may cause malfunctioning to the device itself.
They are also useful to measure product temperatures during manufacturing, to spot problems before they reduce quality
or cause production downtime.
Their principle of operation is very simple, the instrument determines the temperature of an object by measuring the
amount of radiant energy emitted by it.
The detector, installed on each
amount of energy received, and therefore is a function of the temperature of the target. By sampling and manipulating
the output of the detector, the microcontroller-based electronics can display the temperature and the related computed
values such as maximum, minimum, average, and difference temperatures seen during the measurement. The same
information can also be stored and processed via Personal Computer (using electronic spreadsheets e.g. Lotus, Excel,
Paradox, etc.). The displayed value can be printed out directly into an external printer supplied on request.
Thanks to its advanced optical system and electronics,
operate in critical ambient conditions.
To take measurements by using
trigger can be locked on if desired. For more distant targets, hold the unit at arm length and use the sighting notch and
post to aim. This will give a parallel and offset sighting. Also Laser beam is available for sighting target.
Temperature information as well as auxiliary parameter pieces of information are shown on the high contrast liquid
crystal display (LCD).
The case, made in shock-resistant ABS + polycarbonate, is ergonomically designed for an easy practical use.
The instrument is powered by a group of four alkaline or Ni-MH rechargeable batteries (AA type); an external battery
charger module is supplied as a standard accessory.

2 GENERAL FEATURES

2.1 General

Temperature measurements of a liquid or gaseous compound have been successfully made with thermoelectric or
expansion thermometers thanks to the good thermal exchange of the sensor with the fluid.
With solid bodies a good thermal exchange is difficult to be obtained and an additional measuring error should be
considered.
A direct contact measurement is impractical when the object being measured is moving, it cannot be touched with a
thermoelectric sensor because of electrical hazard or of other reasons.
A non-contact IR temperature measurement is the best solution to the above application problems.
Also other applications benefit because non-contact thermometers do not add or remove heat or disturb the process in
any way, and there is no wear and tare on the instrument.

2.2 Optical System

The optical system is equipped with a main objective to focus the infrared energy into the infrared detector through a
single lens, a filter and a field stop which defines the visual cone and therefore the target dimensions.
As the detector is placed in the focal point of the measurement portion of the optical system no focusing operations are
required.
A secondary, but extremely important objective, is the correct pinpointing of the target as described below.
The optical diagrams are shown in the previous specification section.

2.3 Target pinpointing

A correct aiming at the target is an important factor of a non-contact thermometer. The immediate evaluation of the
smallest measurable target area is also a positive key factor in many applications.
The following types of pinpointing are available :

• A “V” groove on the up side of the instrument can be used stretching the arm.

• Twin laser pointers to define, at distance, the measurable target dimensions. Two versions are available with crossing

or parallel twin lasers. The twin crossed lasers are suggested for target distance upper than 5 meters.

• Combination of twin lasers and direct telescope viewing for universal applications mainly required for a high distance

targets (more than 10 meters) and high temperature targets (more than 1000 °C) where laser spots are not visible .

• Combination of twin lasers and a red point pinpointing for universal applications mainly required for high temperature

target where laser spots are not visible

With a laser pinpointing the operation of the instrument is extremely simplified. You simply aim at the target and read the
temperature.
The installation procedures for telescope and red point pinpointing, please refers to the dedicated chapters.

2.4 Taking measurements

OSP

portable thermometers are accurate, rugged and compact.
Its modern and practical design allows an easy handling and aiming, either at arm length or using a tripod mount, to
obtain current temperature value, average, minimum, maximum and difference temperature measurement values.
Its analogue to digital outputs allows a continuous documentation on a continuous trace recorder or on a serial printer.

Using the keyboard it is also possible to enable the instrument to measure one of the computed values in addition to the
actual temperature value measurement:

MAX maximum temperature recorded during current measurement
MIN minimum temperature recorded during current measurement
DIF difference between MAX and MlN
AVG average temperature for entire measurement
Tamb ambient temperature

2.5 Keyboard

Traditional metal-click switches, with a working life of one million operations, are used to enter the operator’s instructions.
The contact closure of the keyboard keys is acknowledged, as a coded signal, directly by the microcontroller.

2.6 Display

The high contrast customised alphanumeric LCD display indicates the measured temperature value.
It is also used for operators’ messages, instrument configuration set-up, special operative modes, etc.
It is equipped with a backlight device to allow easy readings even in poor light conditions.

2.7 Digital Interface

A digital interface with TTL logic levels is available for communication with external units. A serial data port provides
communication capability at a logic level of 0-5 V (four wires: Tx, Rx, GND, Vcc).
A special software set enables the transfer of all the recorded data on a Personal Computer for further statistical
analysis.

2.8 Self calibration

The hardware-firmware design allows the automatic calibration of the instrument. The calibration procedure is protected
by a security code.

2.9 Thermocouple Input

To extend the operative capability the instrument is equipped with an auxiliary input for thermocouple.
This feature, when used with a calibrated thermocouple, can be used to obtain accurate temperature measurements
eliminating the problems of emissivity and the interfering light.
The thermocouple can be used to obtain an accurate temperature reading of the target material and then these data are
used to determine the compensation value for the actual emissivity, including the interfering light, within a range from

0.10 to 1.00.

2.10 Analog Output

An analog output (1 mV/°C/°F/K) is available to drive an external analog input device (eg. a potentiometric or hybrid
recorder) for long term trend profiling and tests.

10

In this case the instrument can be powered directly from mains using the external power supply module supplied with the
thermometer.

2.11 Logging Mode

The instrument can be equipped with an internal memory to store up to 500 input data.
Two types of data acquisitions can be selected by the user.

Continuous acquisition

The operator can select the interval time between each acquisition and store progressively the input data in the Tag file
or can manually, step by step, give the acquisition instruction.

Acquisition by dedicated tag

Standard Agencies and Quality Auditors require the collection, organization and availability of traceability documents.
A supporting software is available to transfer a selection of plant inspections from a PC to the internal memory of the
instrument in order to simplify field check and select the appropriate tag number.
Dedicated input data are memory stored and downloaded into a PC to document the inspection activity.
Data can be saved on disks, viewed and printed in a numeric or graphic mode.

2.12 Calculated Measurements

For the measurement of unstable input signals by a progressive averaging with a programmable average weight. In
addition the operator can select average, minimum, maximum, Tmax -Tmin, differential.

2.13 Case

The case of the instrument is ergonomically designed for an easy hand held operation and transport.
The body is injection molded, shock-resistant, flame proof ABS+ polycarbonate.
A vinyl case with shoulder strap and an aluminum case for instrument + printer + accessories are available on request.

2.14 Logging Data Manager

LogMan software allows the OSP series users to set and prepare the infrared thermometers to acquire the data
organized by ‘Tag’. This software also allows to download data from Instrument on document (table) with date, time and
value. You can view table, save table, print table, export table in excel-txt-html and obtain graph. You can also manage
data coping, moving on other tables.

The radiated infrared energy is focused by the optical system on an infrared detector sensitive to the required spectral
band. The infrared detector generates a signal proportional to the energy received corresponding to the temperature and
emissivity of the target. See Appendix A for emissivity values.
The output signal of the sensor is then conditioned, converted from analog to digital and transmitted to the
microcontroller. The procedures used to process all the operating functions as well as measure and calculation routines
are stored into the microcontroller memory. Any operator’s instruction, through the trigger and the keyboard is directly
recognized, as a coded signal, by the microcontroller. The actual temperature value and the active operative mode are
indicated on the LCD display.

4.1 Power supply

The instrument is powered, if not otherwise specified with the order, by four internal alkaline batteries or rechargeable Ni­MH type AA (nominal voltage 1.25 V) that can be recharged through an external charger module supplied as a standard
accessory.

4.2 Keyboard

The operative keyboard is designed with a traditional single microswitch per button for long life and high reliability. The
contact closure of the keys is acknowledged as a coded signal by the microprocessor that recognizes the operator’s
instructions.

13

4.3 Microcontroller

The microcontroller handles all the logic functions of the instrument, performs the linearization for non linear transducers,
compensates for the reference junction temperature, drives the digital display and acknowledges all the operator’s
instructions.
The core of the circuit is a single-chip microcomputer that utilizes HCMOS technology to provide the low power
characteristics and high noise immunity of CMOS plus the high speed operation of HMOS.
The microcomputer provides highly sophisticated, on- chip peripheral functions including: 256 bytes of static RAM, an 8
channel analog to digital (A/D) converter (used to read the Rj value, the setting of the input comparator, the battery
package voltage and the value of the auxiliary input), a serial communication interface (SCI) subsystem, and a serial
peripheral interface (SPI) subsystem.
The microprocessor works with an 8-bit communication bus to EPROM and EEPROM memories and is interfaced with a
decoder, a latch of address and an inverter-driver.

4.4 Firmware

The operating system firmware handles all the logic instructions to the internal peripheral circuits and performs the
computation of the linearization equations.
The application system firmware is resident on the non-volatile memory (EEPROM) of the microprocessor chip.
It is used to store the installation parameters (autocalibration data, program data, etc.)

4.5 Display

The custom display, placed on an auxiliary board, uses high contrast LCD technologies (STN liquid).

be operated directly from a line source through the charger.
The plastic case of the battery charger incorporates the line voltage plug and a cable with a connector for
interconnections to the instrument.
The charger circuit is designed with an insulating transformer and a voltage stabilizer circuit. The step-down transformer
reduces the power line 115 Vac to a value of 10 Vac. The above voltage is full wave rectified , filtered and stabilized. The
output voltage of 5.6 Vdc is the ideal value to recharge the internal Ni-MH batteries

4.7 Digital interface

The digital interface circuit is essentially based on the serial communication interface subsystem (SCI) on the chip of the
microprocessor at 0 / +5V level. Adapters to convert TTL to RS 232 voltage levels are available from OMEGA.

5 UNPACKING

Remove the instrument from its packing case and remove any shipping ties, clamps, or packing materials.
Carefully follow any instruction given on any attached tags.
Inspect the instrument from scratches, dents, damages to case corners etc. which may have occurred during shipment.
If any mechanical damage is noted, report the damage to the shipping carrier and then notify OMEGA directly or its
nearest agent, and retain the damaged packaging for inspections.
A label indicates the serial number of the instrument.
Refer to this number for any inquiry for service, spare parts supply or application and technical support requirements.

OMEGA

will keep a data base with all information regarding your instrument.

6 PRE-OPERATIONAL CHECK

OSP series

portable thermometers are powered either by four alkaline or by Ni-MH rechargeable batteries (optional).
The external battery charger, supplied as a standard , is set for 115Vac power source.
Before using the instrument carefully verify the nominal voltage value of the charger with the available mains power line.
The instrument should be used in environments where the temperature does not exceed the specified limits (from -5°C to
+50°C) and where the relative humidity is lower than 95%.

In case of “low” battery conditions (voltage lower than 4.6 V) the display will show the appropriate symbol. A battery
symbol means that the battery package has enough energy for about 20 minutes operation. In this condition the
instrument batteries must be recharged.

7.1 Rechargeable batteries

The rechargeable batteries are shipped with an average level of charge. After unpacking, a full charge of the batteries is
recommended. Connect the instrument to the charger module (“OFF” condition) for a period of 10 hours minimum.
The Ni-MH rechargeable batteries do not suffer when used in cyclic operations. The cyclic operation is understood as a
method of operation by which the battery is continually charged and discharged.
Avoid leaving the instrument, with batteries totally or partially discharged, for a long time without recharging them.
To charge the batteries use only the original supplied charging module. The module incorporates protection and current
limiting devices not normally found in other commercial chargers.
The external battery charger is configured, before shipment, for a supply voltage of 115 Vac, upon order specification.
The nominal voltage value is indicated on the front label of the charger.

7.1.1 How to maximize the life span of the battery

Disconnect the ac mains supply when the battery is charged. Use the battery until it is completely discharged. Leaving
the ac mains charger plugged in during operations will decrease the life of the Ni-MH batteries. Keeping the battery
terminal clean will help maximize the operating time. Periodically wipe the positive and negative terminals with a dry
cloth. Removing and replacing the batteries will ensure electrical contact. This should be done when using a battery that
has not been used for a long time.
Note that the operating time decreases at low temperatures. A Ni-MH battery can be recharged about 500 times when
used with the recommended instructions. When replacing the Ni-MH batteries with a new set always replace
simultaneously the four pieces.

7.2 Power supply with alkaline batteries

Power supply with alkaline batteries must be specified with the order.

7.3 Power supply from main line AC

The battery charger module can be used to power the instrument for continuous operations from main line AC.
Rechargeable batteries or alkaline batteries are not required to be removed with AC power supply.

Working band

!

Weight

!

The working band is used to define the maximum difference between the actual and previous measurement values
where average mode has to be operative. It means that if you are measuring ambient temperature ( for example 23°C )
and you point the instrument to the process ( for example 600°C ) you don’t need a slow increasing due to average ( The
difference is 600 – 23 = 577 °C ).
If working band is set at 100°C instrument don’t apply any average and it will pass directly to temperature of the process
( 600°C ) otherwise with standard average you will see the temperature slowly growing from ambient to the target point.
When instrument is measuring the process the difference due to unstable temperature is inside working band so it will
works in average mode.
More unstable is the process higher has to be the weight of the average. Higher is the weight ,slower will be the reading.

10.8 Ambient Temperature Compensation (TAM)

This function is used to compensate the measure from the ambient temperature.

Targets which have low emissivity will reflect energy from their surrounding environments, which is going to add to their
own emitted energy. If the temperature of the surrounding environment is the same value as the internal temperature of
the unit, there is no need to consider this value as it is automatically and continually measured. However, in some
industrial situations the surrounding environment (machines, furnaces, or other heat sources) has a much higher value
than the one of the internal of the unit temperature. The table below "
on measurement accuracy, with and without the use of the Ambient Temperature Compensation mode.

The Ambient Temperature Compensation mode should be used whenever the stated following points are true :

1. The target has a low emissivity.

2. Temperatures of objects facing targets are much hotter than the temperature of the unit.

3. An increased measurement accuracy is required

11 DATA ACQUISITION OPERATIVE MODE

When the optional accessory of the instrument is specified (Internal data memory + RS232 adapter + LogMan software)
the instrument is equipped with an internal memory to store up to 500 input data records. Two types of data acquisitions
can be selected by the user.

Continuous acquisition

The operator can manually, step by step, store his data through the keyboard or can select the interval time between
each acquisition and store progressively the input data in the “Tag 0” file.

Acquisition by dedicated Tags

Standard Agencies and Quality Auditors require the collection, organization and availability of traceability documents. A
supporting software is available to transfer a selection of plant inspections from a PC to the internal memory of the
instrument in order to simplify field check and select the appropriate Tag number. Dedicated input data are memory
stored and downloaded into a PC to document the inspection activity. Data can be saved on disks, viewed and printed in
a numeric or graphic mode.

A full description of this acquisition mode is available with the dedicated software.

5 1 EE280198 filter ring
6 1 EE360053 filter HT
7 1 EE370133 O-ring

Installation of the telescope :

1 Remove with a cut screwdriver the nut protection caps placed on the upper part of the instrument.
2 Place the guide on the upper part of the pyrometer, taking care of orientating it so that it leans entirely on the back of

the instrument.

3 Fasten the screws in order to make the guide integral with the pyrometer.
4 Place the mounting rings on the guide, in order to cling them to the side edges. Let each ring slide along the guide

until each catch is housed in the respective slot. Fasten firmly each fastening screw with a coin or a screwdriver.

5 Separate the upper and the lower half of each mounting ring by removing the two screws, using the enclosed

hexagonal wrench.

6 Put the telescope in the supporting framework formed by the lower halves of the mounting rings and place the

extremity with the widest diameter turned towards the target.

7 Rotate the telescope into the mounting rings, in order to bring the elevation adjustment (UP) high. Fasten the

screws, avoiding to make an excessive clamping.

Alignment of the telescope :

1 Make the pyrometer integral with a support.

42

2 Remove the elevation and the windage adjustment caps.
3 Switch on the two pinpointing lasers and aim them to a target placed at a distance equal to the working distance.
4 The aiming must be carried out by keeping the eyepiece at a distance of about 80 cm from the eye.
5 Operating on the two adjustments (elevation and windage), place the center of the reticule in connection with the

center of the axis joining the two spot lasers. The minimum suggested working distance is 5 meters, shorter working
distance can cause alignment problems.

6 In this way the telescope is aligned to operate at the working distance; a variation in the working distance requires a

new alignment of the telescope.

Filter installation

1 Filter use is suggested in viewing targets with temperature higher than 1000°C
2 Install the filter ring on the front side of the telescope lightly pushing the component

5. Separate the upper and the lower half of each mounting ring by removing the two screws, using the enclosed
hexagonal wrench.

6. Put the sighting device in the supporting framework formed by the lower halves of the mounting rings, so that the
rheostat hand grip is situated on the left side of the pyrometer, with respect to the aiming direction.

7. Rotate the sighting device into the mounting rings, in order to bring the elevation adjustment (UP) high. Fasten the
screws, avoiding to make an excessive clamping.

Alignment of the sighting device :

1. Make the pyrometer integral with a support.

2. Activate the illuminated red point by turning the rheostat hand grip clockwise to increase the brightness or in an
counter-clockwise direction to reduce it. The position “1” indicates the minimum brightness and the position “7”, the
maximum one.

3. The aiming must be carried out by keeping the eyepiece at a distance of at least 7 cm from the eye.

4. Remove the elevation and the windage adjustment caps.

5. Switch on the two pinpointing lasers and aim them to a target placed at a distance equal to the working distance.
The minimum suggested working distance is 5 meters, shorter working distances can cause alignment problems

6. Operating on the two adjustments (elevation and windage), place the illuminated red dot in connection with the
centre of the axis joining the two spot lasers.

7. In this way the sighting device is aligned to operate at the working distance ; a variation in the working distance
requires a new alignment of the sighting device.

14 APPLICATION NOTES

14.1 Infrared energy

Each body, at temperatures above the absolute zero (-273°C or 0K), emits energy in the form of electromagnetic
radiation.
As the temperature of the body rises, the intensity of this infrared energy increases.
The temperature of this particular body can therefore be determined by measuring the intensity of this infrared energy.
An equipment used to measure the temperature with this method is called "infrared thermometer" or a "non-contact
thermometer" since the thermometer is not required to be in contact with the body in order to measure its temperature.

14.2 Applications

The temperature measurement of liquids or gases is well accomplished using a thermoelectric sensor thanks to the good
thermal exchange between the sensor and the fluid.
When solid objects are to be measured it is difficult to obtain a good thermal exchange and the possibility of making an
additional error should be kept into consideration.
Temperature measurements with direct contact are often impossible to be carried out when the target is moving or is
connected to dangerous electrical sources or when, for any other reason, it is impossible or difficult to touch it.

14.3 Emissivity

The infrared energy emitted by a body differs according to the composition of the body and to the physical condition of
the surface.
Non-contact thermometers are calibrated using a blackbody source (made with material that absorbs energy at all
wavelengths) as a reference standard.
However, to obtain the reading of the true temperature, it is necessary to compensate the thermometer for the actual
emissivity of the object to be measured.

Emissivity = Surface Radiation
Blackbody Radiation

OSP

All
The emissivity values relevant to different materials and surface conditions are detailed in “How to determine an object
emissivity” in Appendix A2 of this manual.
The values from the above tables are reference values only: emissivity can in fact be slightly higher with a higher
oxidation of the material .

infrared thermometers are equipped with an emissivity adjustment from 0.10 to 1.00.

14.4 Reflected energy compensation

The radiation perceived from the thermometer is the one emitted by the target plus the radiation reflected by the surface
of the object itself.
To obtain more accurate readings, particularly for measurements of low emissivity temperature objects, the energy
reflected from the target should be considered; that energy changes according to the temperature of the surrounding
environment.
A typical example of that principle of operation comes from re-heating furnaces, where the temperature of the vault is
considerably higher than the target temperature.

OSP

thermometers provide an auxiliary function "TAM" to compensate for the ambient temperature.
When the average value of the ambient temperature is set, the microprocessor processes a correction algorithm and
then displays the real temperature value of the target (see par. 9.7).

As an example, the error occurring when no auxiliary function "TAM", to compensate for the ambient temperature, is
enabled can reach 20°C when measuring a target at 100°C with the ambient temperature of 150°C.

Each
The calibration should be verified and re-adjusted if the instrument shows an error exceeding the declared specifications
or when a critical active or passive component is replaced (either at the component level or at the board level).

OMEGA

16.1 Faulty operating conditions

During the start-up and measuring modes, faulty conditions of the instrument will be announced with coded messages.
If the faulty condition is critical for the application, it is recommended to re-start the pertinent set-up procedure.
All errors which cannot be recovered without the user's knowledge, result in some system action to inform the operator
via message and where possible to restore the system.
Restarting the instrument from -Power ON- may clear the error, but generally such messages are caused by hardware or
software faults, which require the user's action.

A1 How to determine an object emissivity

Emissivity is the measure of an object ability to absorb, transmit, and emit infrared energy. It can have a value from 0
(shiny mirror) to 1.0 (blackbody). If a value of emissivity higher than the actual one is set, the output will read low,
provided that the target temperature is above the ambient one. For example, if 0.95 is set in and the actual emissivity is

0.9, the reading will be lower than the true temperature when the target temperature is above the ambient one.

The emissivity can be determined by one of the following methods, in order of preference:

1. Determine the actual temperature of the material using a sensor such as a RTD, thermocouple or another suitable
method. Next, measure the object temperature and adjust the emissivity setting until the correct value is reached.
This is the correct emissivity for the measured material.

2. For relatively low temperature objects (up to 260°C or 500°F, place a piece of tape, such as a masking, on the
object. Make sure the tape is large enough to cover the field of view. Next, measure the tape temperature using
an emissivity setting of 0.95. Finally, measure an adjacent area on the object and adjust the emissivity setting
until the same temperature is reached. This is the correct emissivity for the measured material.

3. If a portion of the surface of the object can be coated, use a flat black paint, which will have an emissivity of about

0.98. Next, measure the painted area using an emissivity setting of 0.98. Finally, measure an adjacent area on
the object and adjust the emissivity setting until the same temperature is reached. This is the correct emissivity for
the measured material.

A1.1 Typical Emissivity Values

The following table provides a brief reference guide to determine emissivity and can be used when one of the above
methods is not practical. Emissivity values shown in the table below are only approximate, since several parameters may
effect the emissivity of an object. These include the following ones:

1. Temperature

2. Angle of measurement

3. Geometry (plane, concave, convex, etc.)

4. Thickness

5. Surface quality (polished, rough, oxidized, sandblasted)

6. Spectral region of measurement

7. Transmissivity (i.e., thin film plastics)

To optimize surface temperature measurements consider the following guidelines:

1. Determine the object emissivity using the suitable instrument for measurement.

2. Avoid reflections by shielding the object from surrounding high temperature sources.

3. For higher temperature objects use shorter wavelength instruments, whenever any overlap occurs.

4. For semi-transparent materials such as plastic films and glasses, assure that the background is uniform and lower in

temperature than the object.

5. Mount the sensor perpendicularly to the surface whenever the emissivity is less than 0.9. In any case, do not exceed

angles more than 30 degrees from incidence.
