Lsens-P Fiber optic temperature sensor

  • Small tip Polyimid, protected
  • Outstanding repeatability with high flexibility
  • Complete immunity to RFI, EMI, NMR and microwave radiation
  • Does not require recalibration or complex inputs to operate
  • Cryogenic temperature range available ( as low as 2 Kelvin )

A multiple use fiber optic temperature sensor for measurement in wide range of demanding applications, where immunity to electromagnetic fields is mandatory.

Product Summary

A multi use fiber optic temperature sensor designed for a wide range of applications, especially for the use in demanding applications, Sensor offers complete immunity to RFI, EMI, NMR and microwave radiation. The standard temperature sensor has a response time of 0.2s. With a standard deviation of +/-0.2°C it allows precise and repeatable measurements. The coating of temperature sensor is made of PTFE, the fiber tip has a diameter of 0.7mm with Polyimid coating and has a stainless steel ST-connector. For mechanical stability and applications e.g. in oil special protective coatings and hoses are available. The fiber optic probe consists of a PTFE protected glass fiber and a GaAs-crystal (Gallium Arsenide) at the sensor tip. It is totally free of metal and immune to external fields, therefore probes are explicit suitable for the use in high temperature ranges as well as in aggressive operating environments. The sensor cable can be from several meters to kilometers long without influencing the accuracy of the measurement result. Other sensor lengths and connector types are available upon request.
