Expansion Thermometer with Micro Switch & Capillary - 70-8xx

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
Thermometers of this product range find their application whenever a local temperature display is needed at the same time as switching an electrical circuit.

Expansion thermometers can be fitted into or onto almost any point. Versions with capillaries are used in locations which are not easily accessible and where long distances have to be bridged.

They can therefore be used in just about any application; such as in machine building, refrigeration and air-conditioning technology and other industrial applications.
Features
  • Case and stem from stainless steel. 
  • Version per DIN EN 13190. 
  • High switching reliability and long service life. 
  • Temperature controller and indicator in a single instrument. 
  • One or two adjustable micro switches.
