KPS Pressure Switch
Brand: DanfossThe KPS Series consists of a series of pressure and temperature controlled switches.
In this series, special attention has been given to meeting demands for a high level of enclosure, robust and compact construction, and resistance to shock and vibration.
For KPS pressure switches the position of the contacts depends on the pressure in the inlet connection and the set scale value.
For KPS thermostats the position of the contacts depends on the temperature of the sensor and the set scale value.
The series covers most outdoor as well as indoor application requirements and is suitable for use in monitoring alarm and control systems in factories, diesel plants, compressors, power stations and on board ships.
