High Reliability Handheld Signal Conditioner for Gallium Arsenide-Based Fiber Optic Temperature Sensors
- Compact and rugged design with rubber boot casing protection
- High linearity and precision
- Superior total system accuracy (± 0.8 °C)
- Internal reference to guaranty reliability
- Traceable calibration
- Versatile and easy to use with large LCD display
- 50 Hz sampling rate
- ±5 V and RS-232 output interfaces
At the heart of the LumaTEST is the LumaSense Semiconductor Band Gap (SCBG) technology which provides accurate measurements using the temperature-dependent band gap 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.
