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. Any temperature variation notic

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

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 devic

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 instru

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

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 h
