Auto Format Form Air Pressure Switch With Dual Ressure Control
Introduction:
1, P series pressure control can protect compressors in
refrigeration and air-condition plant, and keep them from over-low
pressure or over-high suction pressure.
2, P series pressure controls can start and stop refrigeration
compressors and fans of air condensers.
3, P series pressure controls can be used not only in fluoride
refrigeration, but also in air and liquid.
4, P series pressure controls are fitted with 3 kinds of changeover
switch: a single pole double throw (SPDT), a double pole single
throw(DPST) and a double pole double throw(DPDT). The position of
the switch is determined by the pressure control setting and the
pressure at the connector.
