Electropneumatic Transducer
Ranges 3-15 psig, 0 to 20 psig.
The EP-311/313 incorporate quiet low-wattage poppet valves and a pressure sensor to measure and adjust the branch line pressure proportional to the input. This unit has no air consumption and is immune to mounting orientation or supply line pressure fluctuations. The EP-311/313 incorporates a manual override switch and, in the manual mode, the pressure can be increased or decreased with two pushbutton switches.
Tristate Pneumatic Transducer
The EP-321 accepts a tristate input and provides an output pressure pulse train with a field adjustable pulse width and interval. The EP-325 accepts a tristate input and converts the contact closure time into proportional branch line pressure. Both units have quiet low wattage poppet valves, rugged aluminum manifold, brass barb fittings and a unique steel chassis which substantially reduces the overall size.
