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.
