Bellows pressure switch KPI36

differentialSPDTfor liquids

The KP and KPI pressure switches and thermostats are used for control, monitoring and alarm systems in a wide variety of industry applications. KP pressure switches are mainly used for gaseous €uid whereas KPI pressure switches are more for liquid and gaseous €uid. The products are available in IP30 enclosure as well as IP55 enclosure. The KP pressure range include special designed pressure switches and limiters for steam boilers and other heating applications. For water pump control and protection (dry run) the dual pressure switch KP44 is suitable and secure improved life time of the water pump.
