Temperature sensor Type WJK


Product description

Possible areas of application Temperature sensor Type WJK

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 spring-loaded immersion tube. This sensor was specially developed for measuring temperatures in gearbox mounts. The spring loading maintains a constant contact pressure between the sensor and the measurement point, thus ensuring excellent thermal coupling. A special seal between the immersion tube and the screw connection guarantees outstanding insulation.

Technical features:

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