Description

The PSR-100 is a GaAs-based spectrophotometric module that measures the spectral position of the temperature-dependent bandgap of a GaAs crystal affix at the end of a 100 microns core optical fiber. This module is compatible with Opsens’ SCBG (GaAs-based) fiber optic temperature sensors and hence, it requires no calibration factor.

The PSR-100 can be configured to sample measurements at rates varying from 100 Hz to 1000 Hz. The analog output scale and offset are adjustable, with averaging capability for improved resolution.

The PSR-100 is dedicated solely to temperature measurements. Although they are not as accurate as with the WLPI-based sensors, GaAs (SCBG) temperature sensors can be made very small, hence providing extremely fast response time of the order of milliseconds.
