for either a high or low level condition. ow level condition.
The float moves a magnet into the field of a magnetically actuated pneumatic valve. The
pneumatic valve is pilot operated. An amplifying relay provides quick response.
The unit may be mounted for either high or low liquid level alarm by rotating the switch
body. Wrench flats provide ease of rotation.
High Level Pneumatic Output Signal (Direct Acting) Install with pneumatic connections
on the upper side of the body when the unit is tightened into the vessel.
Rising liquid level raises the float upward causing the float stem magnet to repel the
actuating lever magnet and seal the pilot nozzle. Resultant pilot pressure build-up triggers
the amplifying relay to pass pneumatic signal through the output port.
Low Level Pneumatic Output Signal (Reverse Acting) Install with pneumatic connections
on the lower side of the body when the unit is tightened into the vessel.
Falling liquid level lowers the float downward causing the float stem magnet to repel the
actuating lever magnet and seal the pilot nozzle. Resultant pilot pressure build-up
triggers the amplifying relay to pass pneumatic signal through the output port.
