Pneumatic Level Sensor
- Level Switches
- Pneumatic liquid level switch
Sticky or corrosive liquids
Resistant to sticky or corrosive liquids
Suitable for corrosive liquids as they make contact only with the detector, and not with the controller. Enlarged detector is available to ensure stable detection of sticky liquids.
Limited movement achieves long service life.
Liquid head pressure causes diaphragm to move, but only within 2mm - no worries for wear.
Micorswitch offers large hysteresis, so affection from turbulent flow is minimized.
Principle of Operation
Detector measures and transmits the liquid head pressure to the chamber. The diaphragm in the chamber receives the pressure, actuating the microswitch.
