Static Pressure Level Switches
Static pressure level switches detect liquid level using trapped air. When rising liquid reaches the bottom edge of a user-supplied pipe, it confines an air volume; as the level continues to rise, the trapped air compresses, and the switch actuates at a predetermined pressure.
The switches install easily and integrate into existing systems. Pressure level switch products are listed below.
