The GO FILL FILTER Head Electrical Differential Pressure Indicator (GO-VIE77536550) provides remote electrical signalling of filter element condition for compatible filter housings. Designed specifically to mount onto the GO FILL FILTER Head Mechanical Differential Pressure Indicator base (GO-VI77669971), this module converts the mechanical indicator's actuation into an electrical signal. When the filter element reaches its preset differential pressure limit (determined by the mechanical base), this module activates its internal switch, allowing for integration with control systems, alarms, or remote monitoring panels. It's designed for use with GO FILL FILTER Head model GO2214-047. How it Works Attached to the GO FILL compatible mechanical indicator (GO-VI77669971), this electrical module is triggered when the differential pressure actuates the indicator base. This movement activates the module's internal switch, providing an electrical signal via the DIN connector to alert monitoring systems (PLCs, alarms, lights) that filter service is needed.
