Introduction We choice the well-renowned international pressure switch supplier
Danfoss, their pressure switches are used for regulating, monitoring and alarm systems
in industrial applications.
This series are suitable for gaseous media and air. They are fitted with a single-pole
switch changeover (SPDT), and can control single-phase ac motors of up to 2 kW directly.
Wherever monitoring and controlling of temperature and pressure is needed these
robust and reliable controls are suitable. They are space saving units for both
alternating current and direct current, with a wide regulating range and ultra short
bounce time.
Advantages
Danfoss pressure switches are recommended for gaseous media (also water, but only
when
mounted directly on the pipe - do not use capillary tube mounting).
Danfoss pressure switches are designed for use as a pump guard to control and protect
supply water pumps from running dry.
Danfoss pressure switches are suitable in installations where a smaller differential
pressure
is needed. Can be capillary tube mounted.
Danfoss pressure switches are available with an IP 33 grade of enclosure
by mounting the
unit on a flat surface.
