Diaphragm Switch NK-1052

Click to enlarge

A Diaphragm Switch provides point level indication by detecting pressure applied by the bulk material to the sensing diaphragm. The unit is installed to a vessel wall so that the diaphragm is exposed to the material to be sensed. As material contacts the diaphragm, a force is exerted through the diaphragm to a pressure plate within the bin monitor. Physical deflection of the pressure plate activates an internal switch. When material recedes from the diaphragm, a light duty spring returns the pressure plate and internal switch back to their original positions.

1. Insert the gasket between the bin wall and the flange of the Diaphragm Switch and with the conduit facing down, fasten to thebin wall with bolts or cap screws.
2. Connect conduit and make wiring connections at switch terminals.
3. Screw cover to housing securely to prevent damage from dust or moisture.
4. Check switch operation by manually depressing diaphragm and releasing. The switch should now respond to the application and relase of one pound of pressure over the diaphragm.
