Danfoss KPS, Heavy-duty pressure switches
KPS units are pressure-controlled switches. The position of the
contacts
depends on the pressure in the inlet connection and the set scale
value. In
this series, special attention has been given to meeting important
demands
for:
- a high level of enclosure,
- robust and compact construction,
- resistance to shock and vibration.
The KPS series covers most outdoor as well as indoor application
requirements.
KPS pressure switches are suitable for use in alarm and regulation
systems
in factories, diesel plant, compressors, power stations and on board
ship.
Approvals - EN 60 947-4-1 and EN 60 947-5-1
Ship Approvals - American Bureau of Shipping; Germanischer Lloyd,
Germany
Bureau Veritas, France. Includes thermostats with fixed sensor and
pressure controls with armored capillary tube.

Terminology
Range setting - The pressure range within which the
unit
will give a signal (contact changeover).
Differential - The difference between make pressure
and
break pressure (see pdf).
Permissible overpressure - 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. bursting pressure - The pressure which the
pressure-sensitive element will withstand without leaking. |
