Model 180, Differential pressure indicator has a rugged design for industrial use to measure the differential pressure in a filtration system which indicates directly on a single gauge dial.
A specially designed magnetic movement allows the instantaneous sensing of both pressures while completely isolating the gauge function from the WIKA data sheet PM 07.73 WIKA data sheet PM 07.73 ∙ 03/2023 Page 1 of 7 pressure chamber without the use of mechanical seals.
Unlike ordinary differential pressure gauges, these instruments can be supplied with switching facility through a microswitch or reed switch to initiate an alarm signal or system shutdown. One (microswitch) or two (reed switch) switches can be provided to open or close contacts on either rising or falling differential pressure. Switch setting is easily done through an external adjustment for reed switch option.
