Fiber optic Signal conditioner TempSens Multi-channel signal conditioner tor applications using gaas based temperature sensors ALTHEN SENSORS & CONTROLS TempSens ■ Description The TempSens is a multi-channel and easy to operate signal conditioner that is used with any of our GaAs-based fiber optic temperature sensors. At the heart of the TempSens is Semiconductor Band Gap (SCBG) technology which provides a mean for making accurate measurements of the temperature-dependent bandgap of GaAs crystal. The TempSens is equipped with a large visible LCD and it comes with standard ±5 V outputs and a RS-232 communication port for real-time data acquisition. The TempSens can be controlled directly using the front- panel keypad or remotely using the standard RS-232 interface. The TempSens has a channel sampling rate of 50 Hz and channel switching rate of up to 6.25 Hz. With a ± 0.3 °C accuracy or better (total accuracy including both signal conditioner and sensor errors from 20°C to 45°C) and 0.1 °C resolution, the TempSens delivers the performances needed for a wide range of critical measurement applications.
