A Heavy-duty fiber optic temperature sensor for measurement in a wide range of demanding applications where robustness of sensors, immunity to electromagnetic fields and explosion proof requirements are mandatory.


  • Heavy duty protection gives longevity to sensors under harsh and dynamic operating conditions
  • Complete immunity to RFI, EMI, NMR and microwave radiation
  • Outstanding repeatability improves accuracy of testing instruments
  • Plug and Play operation, does not require recalibration or complex input to operate
  • Liquid proof and withstands aggressive chemical solutions

A Heavyduty fiber optic temperature sensor for measurement in a wide range of demanding applications where robustness of sensors, immunity to electromagnetic fields and explosion proof requirements are mandatory.

heavy-duty fiber optic temperature sensor specially designed for harsh and dynamic operating conditions where stress on the Fiber Optic Cable is more than normal. The sensor offers complete immunity to RFI, EMI, NMR, Corrosive, and microwave radiation making it the best choice for all demanding applications. The standard temperature sensor has a response time of 0.2 s. with a standard deviation of +/-0.2 °C. Each sensor allows precise and repeatable measurements. 
The coating of the temperature sensor is made of heavy-duty material, while the fiber tip has a diameter of 1.1mm and has stainless-steel ST-connector. For mechanical stability and applications e.g., in oil special protective coatings and hoses are available.
