Page 20: Product Installation And Maintenance
4.1 Correct Usage The electrical indicator is specifically designed for use with MP Filtri hydraulic pressure and in line filters, the indicator monitors differential pressure across the filter element. The indicators are made up of a certificated switch assembly in a type approved enclosure with a pressure connection that acts on a piston and spring assembly to operate a switch, the movement of this piston is governed by the deferential pressure across the element. -
