  • Product Details
  • The scope of application includes but is not limited to

Fluorescent temperature sensors belong to all light measurement devices;

Only optical signals without electrical signals are true passive probes;

High insulation and voltage resistance, able to withstand 100kV power frequency voltage;

Essentially immune to electromagnetic interference;

The accuracy of detection and the stability of data transmission are completely unaffected.

The advantages of fiber optic temperature sensors

Strong anti pollution flashover ability

The sensor is covered with a PTFE jacket with strong stain resistance to ensure the safety of the system.

Temperature sensitive materials have high reliability

The temperature sensing material of the temperature sensor is rare earth material, which has long-term stability. The fiber optic temperature sensor does not require maintenance, has reliable performance, and a service life of over 30 years.

Accurate positioning measurement

The temperature sensing probe has a small volume and can accurately locate the installation position, making it widely used for temperature monitoring in power equipment and harsh special environments.

Temperature measurement cycle is less than, with high real-time performance

The temperature measurement cycle is less than 1 second, which can fully ensure the timeliness of the alarm.

Fluorescent fiber optic temperature probe has good electrical insulation, anti-electromagnetic interference, chemical corrosion resistance, no pollution and many other traditional temperature sensors can not be compared with the advantages.
Fluorescent fiber optic temperature sensor probe will monitor the part of the temperature information is converted into light signals and transmitted to the fiber optic temperature transmitter, fiber optic sensor probe can be installed directly on the measured point, accurate temperature measurement, rapid response: its pigtail selection of soft, strong, specially designed optical fiber, with anti-electromagnetic interference, bending resistance, impact resistance and high strength; fiber optic sheath using PTFE, high temperature, aging resistance, corrosion-resistant, with high temperature resistance, aging resistance, corrosion resistance, high insulation, non-adhesion and other characteristics, can be adapted to high pressure, high temperature, strong electromagnetic and other harsh environments. Not only in the electric power industry, such as: high-voltage electrical equipment instrumentation temperature measurement, generator diagnostic system and transformer winding temperature measurement, high-voltage circuit breaker contact temperature measurement, cable joint temperature measurement, etc., widely used, but also in biology, medicine and other areas that require high-precision temperature measurement should also be suitable.

Introduction of fluorescent fiber optic sensing probe


Fiber optic probe consists of three parts: ST connector, fiber optic cable, and end temperature sensing end; ST connector is the connection part with the photoelectric module; fiber optic cable is the light transmission part, internal quartz fiber, quartz fiber external coating and cladding, the most external Teflon protective sleeve; end temperature sensing end contains temperature-sensitive rare earth materials, used to generate optical signals containing temperature information; fiber optic is resistant to high temperature of 200 ℃ as a whole, with the diameter of 3mm; long-term bending radius is 13.2cm; short-term bending radius is 4.4cm. Long-term bending radius is 13.2cm, short-term bending radius is 4.4cm, and the fiber optic lead wire is 0.4m from the ground, it can withstand the industrial frequency voltage of 100KV for 5min.
