The Dwyer Series 626 Pressure Transmitters possess a highly precise 0.25% full-scale accuracy piezo-resistive sensor contained in a compact, rugged, NEMA 4X (IP66) stainless steel general purpose housing or cast aluminum conduit housing.

The Dwyer Series 628 Pressure Transmitters are ideal for OEMs with 1% full-scale accuracy sensors. The corrosion-resistant 316L stainless steel wetted parts allow the Series 626 and 628 transmitters to measure the pressure in a multitude of processes from hydraulic oils to chemicals. The Series 626 and 628 are available in absolute and pressure ranges with a variety of optional outputs, process connections, and electrical terminations to allow you to select the right transmitter for your application.

Note: The standard conduit housing (-CH) has been phased out, see the conduit box housing (-CB) for the replacement model.
