Flexible Installation, Easy To Use

The pressure switch is a simple pressure control device. When the measured pressure reaches the rated value, the electronic pressure switch can send 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 inner disc of the sensor moves instantaneously, and the switch joint is pushed or disconnected by connecting the guide rod when the pressure drops to or rises. When the rated recovery value is reached, the disc is reset instantaneously, the switch is automatically reset, or simply when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switching element is directly or after the comparison to change the switching element. The on-off state achieves the purpose of controlling the measured pressure. The elastic components used in pressure switches include single-ring spring tubes, diaphragms, bellows, and bellows. Switching elements include magnetic switches, mercury switches, and micro switches.

The main categories of pressure switches include normally open and normally closed. The main features are:

1. It adopts the British-style pipe thread joint and copper pipe welding installation structure, which is flexible in installation and convenient to use, and does not require special installation and fixation.

2, insert type wire connection for users to choose.

3, sealed stainless steel sensor safe and reliable.

4, within the pressure range can be manufactured according to any user selected pressure value.

Main applications of pressure switch: Mainly used for high and low pressure protection control of home, commercial, and automotive refrigeration systems, steam conditions and power stations, batteries, receivers, flash tanks, separators, scrubbers, and refineries. It can also be applied to high and low pressure protection control of various equipment tools.
