Temperature sensor Type W04


Product description

Possible areas of application Temperature sensor Type W04

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 connecting cable . This sensor was specially developed for use in solar thermal energy 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 electric strength
  • Water-proof and steam-proof connection between bush and connecting cable
  • Connecting cable available with different insulating materials depending on application.
    Shielded variant also available on request
