Description & Operation

The plated housing contains a diaphragm, a calibration spring and a snap-acting SPST–NC switch with manual reset button. The sample connections located on each side of the diaphragm accept 0.25" OD metallic tubing via the integral compression ferrule and nut. An enclosure cover protects the operator from accidental contact with the live switch terminal screws and the set point adjusting screw. The enclosure cover accepts a 0.5" conduit connection.
