Suitable for measuring temperatures of high-voltage components like transformer internals, microwave, RFI, and EMI applications. Temperature measurement can use two different methods: GaAs or FOT (Fluoroptic)Fiber optic temperature sensors are advanced IoT devices that utilize optical fibers, which are thin strands of glass or plastic. They transmit light and detect even the most minor temperature changes. With the fundamental properties of light, such as intensity, polarization, and wavelength, these. Our fiber optic sensors use a Gallium Arsenide (GaAs) crystal at the fiber tip, making them ideal for highly accurate temperature measurements in environments exposed to microwave radiation and high-frequency interference. Our applications include monitoring in Nuclear Magnetic Resonance imaging (NMR) and Radio Frequency (RF) energy. Recognized as a leading developer and manufacturer of fiber optic temperature sensing and partial discharge monitoring products, providing solutions for a multitude of industrial applications. Cost-effective continuous partial discharge monitoring for Switchgear and Transformers. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic.
