Description
The Dwyer 626 and 628 are compact industrial pressure transmitters with 316L stainless steel wetted parts for compatible gases and liquids. Gauge ranges run from 0–5 psi up to 0–8000 psi, with absolute and metric ranges available, and accuracy is 0.25% FS for the 626 or 1.0% FS for the economical 628.
Outputs include 4–20 mA and several voltage signals, with power from 10–30 V DC, and electrical connections range from cable glands to DIN, M12 and conduit housings. The NEMA 4X (IP66) unit has a 300 ms response, an optional plug-on LCD, and optional NSF/ANSI 61/372 approval for drinking water.
