Dual adjustable pressure switches pressure switch water pump
Description
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 will move instantaneously, and the switch
connector will be connected or disconnected by connecting the guide
rod. When the pressure drops to or rises to the rated recovery
value, the disc will reset instantaneously, and the switch will
reset automatically, or simply, when the measured pressure exceeds
the rated value, the free end of the elastic element will move,
Push the switch element directly or after comparison to change the
on-off state of the switch element to control the measured
pressure. The elastic elements used for the pressure switch include
single-coil spring tube, diaphragm, diaphragm box, bellows, etc
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.
