The document describes Pall's RCA series of differential pressure switches and indicators. The RCA series monitors differential pressure across a filter element to signal when it needs changing. Key features include:
- Fatigue testing to 1 million cycles at pressures up to 400 bar. Operating temperatures from -20°C to 120°C.
- Models with electrical connectors for different applications, including models with LED indicators.
- Pressure settings from 2.4 to 3.4 bar. Single pole switches change state when pressure exceeds the set point.
- Automatic reset when differential pressure drops below the set point. Connect to Pall filter housings' ports to monitor filter condition.

System Interface: To fit all standard Pall threaded indicator
ports
Pall RCA series differential pressure indicators signal the need for
filter element change by sensing the differential pressure between
ports upstream and downstream of the filter element. They connect
to the DeltadyneTM
device port available on Pall filter housings.
