                     T30
1
- 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
Recommended for hostile environment 
where  it is exposed to high vibration and  
immunity  to electric fields is mandatory
Product Summary
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
