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 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 OSP unit, responds by producing a voltage signal which is directly proportional to the 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, OSP can be very useful for objects 5mm and larger and can operate in critical ambient conditions.

To take measurements by using OSP thermometers just pull the trigger and then point at the target to be measured. The 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.

OSP portable IR thermometers have been developed using the most advanced microcontroller technique to provide high accuracy on extended ranges and a powerful operating flexibility.

The calibration uses computerized procedures and the relevant calibration data are memory stored to ensure high accuracy.

General features

OSP non contact infrared thermometers are designed to simplify temperature measurements at distance from a target and to identify hot spots, which normally means anomalous operative conditions avoiding costly downtime or processing problems that lead to rejected products. There is no need to focus as required by photographic equipment. Accurate measurements result if OSP field of view diameter is smaller than the target.

Innovative design

This new line of portable instruments represents the most versatile and powerful infrared temperature system.

The most appropriate aiming system at the application can be selected with a twin laser pinpointing or with a combination of twin lasers and telescope or red point for true universal applications.

An on board data logger is available to store up to 500 data points, an analogue output can drive directly a recorder or a controller, The real-time temperature can be displayed together with the Maximum, Minimum, Difference and Average values.

Each model incorporates the following :

high quality optical system

high sensitivity infrared radiation detector

auxiliary input for thermocouple type K and S

microcontroller circuit

high contrast LCD display with backlight device

extended life traditional microswitch keyboard

four alkaline or rechargeable Ni-MH type AA batteries
