Dwyer pressure transmitter Series 634ES

Series 634ES Transmitters sense a single pressure for air, compatible gas or liquid and provide 4-20 mA output signal. Positive pressure can be measured within an accuracy of ±0.5% of span. The Series 634ES uses an isolated piezoresistive pressure sensor to produce a resistance change across a wheatstone bridge. Convenient 2-wire operation simplifies installation. Zero and span adjustments are fully protected inside a rugged die cast aluminum housing with durable gray polyurethane finish. Enclosure is designed to meet NEMA 4X requirements.

Positive pressure can be measured within an accuracy of 0.5% of span,The Series 634ES uses an isolated piezoresistive pressure sensor to produce a resistance change across a wheatstone bridge. The signal is conditioned and converted into a 4-20 mA output signal. For applications requiring direct pressure or percent of full span read-ings, the optional A-701 digital readout makes an ideal companion device, providing a bright .6± high, 3-1/2? digit LED and supplying powe to the Series 634ES Transmitter.
