OSC-OFT-M3 fibre optic temperature sensor is a miniaturized and fast temperature responsive sensor that utilizes the inherent temperature sensitivity of gratings to monitor temperature. It adopts a fully enclosed waterproof design, stainless steel metal tube packaging, and the tail fibre is covered with high-temperature resistant PTFE sheath.

It has the characteristics of high measurement accuracy, long-term zero stability, and good dynamic characteristics. Suitable for long-term temperature monitoring in narrow spaces such as power plants, GBT chips, and oil tanks, it can be widely used for temperature measurement in fields such as electricity.
