Description

At the heart of the PicoP is the Opsens’ Semiconductor Band Gap (SCBG) technology which provides accurate measurements using the temperature-dependent bandgap shift of a GaAs crystal.

Now fitted with an internal reference, the PicoP 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 PicoP 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 realtime data acquisition. The PicoP 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 PicoP is a compact and portable signal conditioner to be used with any of Opsens’ GaAs (SCBG) based fiber optic temperature sensors. With a 50 Hz sampling rate the PicoP delivers the performance needed for a wide range of critical measurement applications.
