Details

At the heart of the LumaTEST is the LumaSense Semiconductor Band Gap (SCBG) technology which provides accurate measurements using the temperature-dependent bandgap shift of a Gallium Arsenide (GaAs) crystal.

Now fitted with an internal reference, the LumaTEST allows regular self verification and correction of its fully traceable calibration. The internal reference guarantees long term Total System Accuracy of 0.8°C in the most adverse conditions encountered in a transformer environment such as temperature variations, component aging, mechanical shocks and transformer vibrations.

The LumaTEST is equipped with a large visible LCD display and can be battery operated. It comes with a standard ±5 V output and a RS-232 communication port for real time data acquisition. The LumaTEST can be controlled directly using the front panel keypad or remotely using the standard RS-232 interface.

A rugged casing with a removable rubber boot provides good mechanical protection against intensive handling in tough environments.

The LumaTEST is a compact and portable signal conditioner to be used with any of Opsens’ GaAs Semiconductor Band Gap (SCBG) based fiber optic temperature sensors. With a 50 Hz sampling rate the LumaTEST delivers the performance needed for a wide range of critical measurement applications.
