Temperature sensor Type WBA


Product description

Possible areas of application Temperature sensor Type WBA

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.



Surface temperature sensor with connecting cable. This sensor is designed for measuring surface temperatures by means of installation or bonding. This sensor is used e.g. on panel heaters.

Indirect temperature measurement means that measurements do not need to be taken directly in the process. This prevents chemicals, for example, from influencing the sensor. 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:

  • Simple assembly
  • High electric strength
  • Water-proof and steam-proof connection between bush and connecting cable
  • Available with optional drill hole to enable attachment to surfaces
  • Connecting cable available with different insulating materials depending on application.
    Shielded variant also available on request
  • Customer-specific fitting lengths and fixing thread on request
