AGD10 Replacement Alarm Gauge

This high pressure Alarm Gauge preset at 400 psi decreasing pressure. Large 2 1/2 inch gauge with pressure switch that utilizes a diaphragm to detect pressure change. The response, at a predetermined set point, actuates a SPDT snap acting switch, converting a pressure signal into an electrical signal. Control set point may be varied by turning the internal slotted adjustment. This can easily be set in the field without removing the Alarm Gauge or regulator from the system. Pressure switch and gauge are replaceable separately making this a very economical system.
