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
9
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.

4.3 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). are standard equipped with a backlight device for easy readings in poor light conditions.

The auxiliary module, supplied as a standard accessory, allows operations from 115 Vac 50/60 Hz. 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

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.
