Cleveland Controls Model PSG-100 is a compact, economical switch specifically designed for use with gas furnaces, package burners and other fuel-burning equipment, or any application which requires low gas pressure or flow-proving. The PSG-100 is suitable for use with natural, manufactured or LP gas.

The plated housing contains a diaphragm, a calibration spring and a snap- acting SPDT switch.

The sample connections located on each side of the diaphragm accept .25″ OD metallic tubing via the 1/8″ -27 NPT female sample line connectors.

An enclosure cover guards against accidental contact with the live switch terminal screws and the set point adjusting screw. The enclosure cover will accept a .5″ conduit connection.
