Temperature sensor Type WD0


Product description

Possible areas of application Temperature sensor Type WD0

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 protection tube form 4 and form DS. This sensor is supplied with a one-piece protection tube for welding and is designed for measuring liquid and gaseous media in industrial applications that are subject to high loads.

Technical features:

  • Numerous different protection tube materials available
  • Test certificate in accordance with EN 10204 for the protection tube available
  • Available with optional instrument transformer
