Fiber Optical Sensor
The FOTS fiber optic temperature sensor probes deliver industry-leading accuracy, repeatability, and reliability across diverse applications. Based on the intrinsic temperature-dependent quantum effects of bandgap materials, the FOTS sensor features a compact sensing crystal at the fiber tip, ideal for tip measurement applications. Immune to RF interference, these probes enable precise temperature monitoring in extreme environments. They are easy to install, robust, and available with customized designs upon request, tailored for OEM applications. When paired with the SMNT readout unit, the FOTS sensor provides exceptional repeatability and reliability even in challenging conditions, including high EM, RF, MR, and microwave field environments. The standard operating range spans from -40 °C to +300 °C.
