Temperature sensor Type WHS


Product description

Possible areas of application Temperature sensor Type WHS

The sensor is designed to measure temperature and humidity in air supply channels and air conditioning systems. A variety of requirements were taken into consideration during the realization:

  • Low heat dissipation through process connection made of glass fibre reinforced plastic => clearly smaller measuring error
  • Digital 1-wire bus interface => Lower wiring cost
  • Exchangeable filter protects against dust and dirt
  • Safe and compact electrical connection through M12 connector
  • Short response time => Ideal for controlling rapidly changing process parameters
  • Very high vibration resistance => Reliable and durable operation
  • Type approved according to DIN EN 50155

Temperature sensors have very distinct fields of operation and the conditions they are subject to are often harsh. 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.
