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 are portable infrared temperature devices designed to ease maintenance operations. They also enable the monitoring of operating temperatures of mechanical and electrical plants or production equipment without removing the equipment from the service.

2 2.1 GENERAL FEATURES 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.
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.
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.
3 PHYSICAL DESCRIPTION OSP portable IR thermometers consist of a rugged, compact and self-extinguishing case ergonomically designed for an easy practical use. The instrument can be supplied either with a vinyl protective case with shoulder strap or with an aluminum case to assure better protection against mechanical knocks or scratches. The battery container is located on the lower part of the handle, and is accessible through a cover fastened by a metal screw.

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.
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.
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.
7 POWER SUPPLY The instrument may be powered by alkaline or rechargeable batteries or directly from the main line. OSP uses 4 batteries type AA that are located inside the base of the handle. 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.

14 14.1 APPLICATION NOTES 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.
15 DIGITAL INTERFACE The OSP portable IR thermometer can be equipped with a digital interface. The interface circuit is essentially based on the serial communication interface subsystem (SCI) on the chip of the microcontroller. The output voltage levels are TTL at 0 to +5 V. An optional adapter to convert the voltage level from 0 to +5 V to RS232 standard levels can be supplied. This adapter is required to interface OSP with a Personal Computer. 15.

16 MAINTENANCE Each OSP portable infrared thermometer has been factory tested and calibrated before shipment. 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 engineers will give prompt support for any request of assistance. 16.
APPENDIX 53
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.
