What is an air pressure switch？
A pneumatic control switch, also known as a pneumatic switch and pneumatic valve, is a kind of switch that uses different pressure generated by the gas pressure on both sides of the switch valve to control the opening and closing action.
What does an air pressure switch do?
The pressure switch adopts the high precision, and high stability of the pressure sensor and the transmission circuit, and then through the special CPU modular signal processing technology, to realize the detection, display, alarm, and control signal output of the medium pressure signal. The pressure switch can be widely used in the petroleum, chemical industry, metallurgy, electric power, water supply, and other fields for all kinds of gas, liquid gauge pressure, absolute pressure measurement, and control, is the ideal industrial field intelligent measurement and control instrument.

Working principle of the air pressure switch
The wind pressure switch is a new economical water heater wind pressure switch product. It adopts the classic innovative shrapnel structure to achieve the characteristics of a small structure and large contact force to ensure the contact reliability of the product. The air pressure switch is used in wall-mounted furnaces, gas boilers, all kinds of gas equipment, exhaust system, and other equipment. The parameters on the air pressure switch of the water heater are generally: P=0.9m bar, Pmax: =10 bar, which is the unit of air pressure. 1mbar=100Pa, that is, the rated air pressure is 90Pa, and the maximum pressure can be adjusted to 1000Pa.
Air pressure switches the structure of the wind pressure switch is small, the appearance is simple, and the cavity volume design is reasonable enough to ensure that the pressure change can be efficiently converted into the switch contact force. The wind pressure switch is a new economical water heater wind pressure switch product. It adopts the classic innovative shrapnel structure to achieve the characteristics of a small structure and large contact force to ensure the contact reliability of the product.
