Temperature sensor Type WDS


Product description

Possible areas of application Temperature sensor Type WDS

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 M12 connector. This sensor is designed for measuring media, for example, in heating and air conditioning systems as well as in cooling circuits in machines and plants.
Thanks to the optional digital sensor with 1-wire Bus interface, only one connecting cable is required for communication and voltage supply. A large number of sensors can communicate on a bus line with the control system.

Technical features:

  • High vibration resistance
  • Reliable and compact electrical connection using M12 connector
  • High degree of protection against ingress of moisture, dust and dirt
  • Short response time
  • Customer-specific fitting lengths and fixing thread on request
