Introduction to Fluorescence Fiber Optic Temperature Measurement System
This product has unique technical advantages for temperature measurement in special environments such as high voltage and strong electromagnetic interference. The temperature hotspot of the fluorescent fiber optic temperature sensor used in the transmitter is not electrically connected to the measurement signal receiving part, which can work with high precision and stability for a long time, greatly improving its application range. At the same time, fiber optic temperature transmitters effectively eliminate the hidden dangers of high voltage circuit breakers or cable heads being used in excessively high temperature environments, which can shorten their lifespan and even burn out circuit breakers or cables, and are not conducive to the safe operation of switchgear. The transmitter has high accuracy and sensitivity, is resistant to high pressure and corrosion, can be remotely monitored, has a long service life, is small in size, makes instrument maintenance simple and convenient, and is safe to transport. Its internal modular integrated design is aesthetically pleasing and reasonable.

Fluorescent fiber optic temperature probe
The fiber optic probe consists of three parts: ST connector, fiber optic cable, and end temperature sensing end. The ST connector is the connection part with the optoelectronic module; Fiber optic cable is the transmission part, with quartz fiber inside. The quartz fiber has a coating and cladding on the outside, and a PTFE protective sleeve on the outermost part; The temperature sensing end contains temperature sensing rare earth materials, which are used to generate optical signals containing temperature information; The overall temperature resistance of the optical fiber is 200 ℃, with an outer diameter of 3mm. The long-term bending radius is 13.2cm. The short-term bending radius is 4.4cm. When the distance between the optical fiber lead and the ground is 0.4m, it can withstand a power frequency voltage of 100KV for 5 minutes
