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

SPDT dual pressure switch for controlling air or liquid Description What is the two pressure used in pressure switch? There are two main types of pressure switches: mechanical pressure and electronic pressure switches. A mechanical pressure switch has a mechanical pressure-sensing part that deforms according to the fluid pressure. 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

Adjustable pressure switch for water pump Description How do pressure switches work? An electro-mechanical pressure switch works by applying pressure to either a diaphragm, bellow or a piston to exert motion. The motion can create electrical contact in a microswitch launching an alarm or creating an action, for example switching off a compressor. An electronic pressure switch generally uses a piezo-electric crystal; when deformed a piezo crystal emits an electric current.
