Summary Products

Recommended for hostile environment where it is exposed to high vibration and immunity to electric fields is mandatory

  • Industrial use with rigid polyimide tip, 1.7 mm diameter
  • Rugged tip ideal for Industrial application
  • Complete immunity to EMI/RFI/lightning
  • High vibration environments


A multiuse fiber optic temperature sensor designed for a wide range of applications, especially for the use in demanding applications. The sensor offers complete immunity to RFI, EMI, NMR and microwave radiation. The standard temperature sensor  has a response time of 0.2 s. With a standard deviation of +/-0.2 °C it allows for precise and repeatable measurements. The coating of the temperature sensor is made of PTFE, and the fiber tip has a diameter of 1.7 mm with Rugged Polyimide 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 explicitly 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.
