Point temperature sensors based on FBG (Fiber Bragg Grating) structures. They are designed to measure the temperature of gaseous, liquid and solid substances. The maximum temperature range is -50 to 200 °C. These fully dielectric sensors are designed for specialized measurements in highly electromagnetically disturbed environments.

APPLICATION

  • Advanced industrial applications.
  • Power industry (temperature measurement of transformer windings, electric motors, etc.).
  • Automotive (temperature measurement of charging stations, batteries).
  • Avionics, aerospace.

KEY FEATURES

  • Long-term stability, accuracy and repeatability of measurements.
  • Measurement accuracy linear over the entire range of measured temperatures.
  • Large dynamic range, sensors can be located up to several kilometers from the evaluation unit.
  • Completely dielectric sensor – galvanic isolation of the measuring point with the evaluation electronics.
  • Immune to electromagnetic radiation.

ACCESSORIES

  • Interconnecting fibre optic cable between evaluation electronics and sensors.
  • Fibre optic switch.
  • Converter to RS485.
