Danfoss Pressure Switches

The CAS series covers most outdoor as well as indoor application requirements.
CAS pressure controls are suitable for use in alarm and regulation systems in factories, diesel plant, compressors, power stations and on board ship.

CAS155  2 x G1/4 bsp

Range setting
The pressure range within which the unit will give a signal (contact changeover).
Differential
The difference between make pressure and break pressure
Permissible burst pressure
The highest permanent or recurring pressure the unit can be loaded with.
Max. Test pressure
The highest pressure the unit may be subjected to when, for example, testing the system for leakage. Therefore, this pressure must not occur as a recurring system pressure.
Min. Burst pressure
The pressure which the pressure-sensitive element will withstand without leaking.
