Galliumarsenid basierte faseroptische Temperaturmessgeräte

FOTEMP1-OEM-PLUS, Faseroptisches Temperaturmessgerät

The thermometer FOTEMP-OEM-PLUS with fiber optic sensors is ideal for the use in microwave, high frequency, high voltage and magnetic field or aggressive environments where measurement with metal temperature sensors (RTC, TC, capillary,...) is not possible.

The measure principle use the change of the optical properties of a gallium arsenide crystal (GaAs) with the temperature. The FOTEMP-OEM-PLUS contains a light source, an optical analyzerand belonging electronic with interface and display. The compact device has a 2.8" coloured display for current measurement values as well as a monitoring of the sensor integrity. Standard analog output (one per channel) and serial communication port  can be used for real-time data acquisition. In addition, the ìFOTEMP Assistantî software is available to  control and monitor FOTEMP-OEM-PLUS directly. The communication protocol is available for own software development.

Depending on the measurement environment, several sensor designs are available with different ruggisation of the fiber tube and sensor tip (see specific data sheets). Customized sensors can be offered.

The system consisting of device and matched probe can be calibrated to achieve an improved accuracy of less than 0.1 K. On request a back-tracing according ISO 17025 can be offered.
