Differential pressure gage 0-15 psi

The Dwyer Instruments A3215 is an electronic differential pressure gage designed for technicians who monitor air or non-combustible gas systems up to 15 psi. A 4 in dial provides clear local indication while two DPDT relays rated at 10 A allow direct control of alarms or equipment.

Installation requirements

Verify that the process connection matches the 1/8 in NPT port and that the supply voltage is 110 VAC at 50 or 60 Hz. The ambient temperature must stay between 20 and 120 deg F and the total system pressure must not exceed 35 psig or fall below 20 in Hg.

Build quality and daily use

The unit carries CE, UL and CSA markings and is rated for continuous operation within the stated temperature band. Relay contacts handle 10 A at 28 VDC or 120/240 VAC, so wiring can follow standard control-panel practice without additional interposing relays.
