Temperature sensor Type W20


Product description

Possible areas of application Temperature sensor Type W20

Temperature sensors have very distinct fields of operation and the conditions they are subject to are often harsh. A variety of requirements must be considered when developing the sensors:

  • Special installation locations
  • Special environmental conditions
  • Vibration resistance
  • Short response times
  • Long service life

The advantage for you is that our experienced engineers are aware of these requirements and factor them into the product design, providing a reliable and targeted solution to the problem.



Temperature sensor with connection head form B. This robust sensor is used for measuring exhaust gas temperatures. It is used in large diesel engines such as those on ships and in combined heat and power stations. It is also used in turbines and compressors.

Technical features:

  • Very high vibration resistance
  • One-piece protection tube
  • Available with optional instrument transformer
  • Customer-specific fitting lengths and fixing thread on request
