IP54 White Stainless Steel Pressure Switch For Air And Liquid
Description
The pressure switch is a simple pressure control device, when the
measured pressure reaches the rated value, the electronic pressure
switch can issue an alarm or control signal. The working principle
of the pressure switch: when the pressure in the system is higher
or lower than the rated safety pressure, the disc in the sensor
moves instantaneously, and the switch connector is pushed on or off
through the connecting guide rod. When the rated recovery value is
reached, the disc resets instantaneously, and the switch resets
automatically. On-off state, to achieve the purpose of controlling
the measured pressure. The elastic elements used in the pressure
switch include a single-coil spring tube, a diaphragm, a diaphragm,
and a bellows.
Q830 series dual pressure controls can be not only used in
fluorinated refrigerant, but also in the air
and liquid (allowed liquid temp. -20 to 120°C)
Adjustable range and differential settings.
Renovated SPDT micro-switch ensures the reliable switch function.
Flexible mounting bracket suits various kids of application.
Upper lid is optional (IP44)
Various connections are available on request.
Automatic and manual reset version
The material of bellows is copper and pressure interface is brass.
