Product introduction 

The air pressure switch uses the static pressure of the gas to push the micro switch to realize the on and off of the current.The air pressure switch has a fine-tuning function. When adjusting, the switch point of the air pressure switch can be changed by changing the pressure of the spring.Under normal circumstances, the sampling of the air pressure switch is performed with a negative pressure probe, and the sampling equipment is installed in the negative pressure area of the powerful exhaust cylinder.The sampling hole of the sampler is an inclined circular tube, which forms an angle with the wind direction. When the wind direction changes, its pressure value will change with the change of the wind direction.


The air pressure switch is a detection element, which is generally used in machinery that requires wind pressure, such as pneumatic presses, pneumatic shears, gas water heaters, gas boilers, gas stoves, wall-hung boilers and other electrical products that use gas. Use the static pressure of the gas to push the micro switch to realize the on and off of the current.
