Series EPTA Electro-pneumatic Transducer, available from Dwyer Instruments , converts an analogue input signal to a linearly proportionate pneumatic output by modulating its control valves to regulate branch pressure.
All models incorporate two low voltage valves, an integral in-barb filter, an analogue 30-psi (200kPa) gauge, an anodised aluminium manifold and brass barbed fittings.
The Series EPTA Electro-pneumatic Transducer offers adjustable span and offset as well as manual override.
The Series EPTA Electro-pneumatic Transducer has no air consumption and is immune to mounting orientation. Field selectable output pressure ranges and input signal ranges ensure single unit compatibility with several systems.
The standard models maintain branch pressure on power loss while the fail-safe models will drop the branch pressure to 0 psi (0kPa) on power loss alleviating the need for an external pneumatic safety switch.
Mounting configurations include a metal bracket mount and snap-track mount. The A-400 DIN Rail Mounting Kit is also available for the snap-track mount model.
