4 Connecting a Pressure Line
Shown below are the locations for P1 and P2 Pressure Transducer connectors.
Use a pressure connector kit to connect the required pressure line(s) to the ¼ inch NPT fittings on the
back side of the ERX 350 enclosure.
Hold pipe wrench on flats when installing a pressure line on the pressure transducer connector to ensure
proper sealing and to avoid stress loading on the composite case.
Figure 4-1: Locations for P1 and P2 Pressure Transducer connectors
Note: To avoid over-pressurizing the transducers, it is extremely important to ensure the pressure
transducer(s) can handle the pressure from the gas line(s).
Check Items 570 (P1 Transducer Range) / 571 (P2 Transducer Range) BEFORE applying live gas
pressure to the ERX 350.
