Danfoss Power Coated Metal Enclosure Differential Pressure Switch, Color : Grey, Contact Material : Silver

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.

Pressure switch and Thermostat, Type KP and KPI

The contact system in KP pressure switches has a snap function. This means that the bellows is active only when the

cut-in or cut out value is reached.

The bellows is connected to the pressure of the controlled plant via the connector.

Danfoss KPI pressure switches are designed so that the bellows moves in the same proportion as the pressure

switches change.

To ensure a snap function on contact change over, an omega spring is located between bellows and contact system
