FOTEMP T2
Multichannel DIN Rail Mount Signal Conditioner for Industrial or Medical Applications
The compact FOTEMP-T2 (formerly Insulogix T2) is a multichannel fiber optic thermometer system suitable for the end user or OEM applications. Together with the TS series fiber optic temperature senors, the FOTEMP-T2 thermometer system is the ideal solution for monitoring multiple sensors in microwave, high frequency, high voltage, magnetic or aggressive environments where metal temperature sensors (RTC, TC, etc.) are either inaccurate or hazardous.
The measurement principle is based on the inherent optical properties of gallium arsenide (GaAs) with temperature. The TS series sensors are offered in different configuration optimized for a a particular operating environment or application – food, process industrieis, microwave, harsh chemical, and medical.
The fiber optic thermometer FOTEMP-T2 series is available with either 4 or 8 measurement channels. With a built-in USB interface as standard, the product offers a second interface option of either RS485/Modbus RTU or Ethernet/Modbus TCP. The product includes up to eight 4-20mA analog outputs and four programmable control relays. Real-time data collection via USB is accomplished with the supplied copy of the FOTEMP-ASSISTANT graphical display/data logging software. Software support for National Instruments LabView™ and Python scripts for Modbus system interfacing are available. An update rate of 250ms per active channel allows for fast response.
