TS4 Fiber optic temperature sensor - Weidmann
The fiber optic temperature probe TS4 is especially designed for the use in chemical aggressive and nuclear environments.Its increased resistance comes with no loss in accuracy and the temperature range. Its PTFE-jacket results in a complete immunity to RFI, EMI, NMR and microwave radiation. The temperature sensor guarantees a measuring range from -200°C to +200°C with a standard deviation* of ±0.2°C. The fiber optic temperature probe is completely non-conductive.
Thanks to its special protection the TS4 probe resists even high aggressive chemical concentrations inside the measurement environment – with a maximum diameter of 2mm.
All fiber optic temperature sensors can be connected to the fiber optic temperature measurement devices (FOTEMP), delivers accurate and complete reliable, stable and repeatable values. Starting at a light wave length of 850nm GaAs becomes optical translucent. Since the position of the band gap is temperature dependent, it shifts about 0.4nm/Kelvin.
The sensor cable can be up to several meters and kilometers long without influencing the accuracy of the measurement result.
