20-200Pa air differential pressure switch​


Description


Differential air pressure switch is a kind of detection element, which is generally used in machinery that requires wind pressure, such as pneumatic presses, gas water heaters, gas boilers, gas stoves, wall-hung boilers and other products that use gas. It is driven by the pressure of gas. Micro switch to achieve. It can also be used to purify the front and rear sides of the air conditioner filter (measure the air pressure difference), and it is used to replace the differential pressure gauge and the differential pressure gauge, which is the best choice for the performance and price ratio.
