Dwyer 681 Sanitary Pressure Transmitter

The Dwyer 681 sanitary pressure transmitter is compatible with liquids and gases and is designed to meet 3A standards for applications in food, dairy, beverage and pharmaceutical processing, liquid level control, and sanitary pipelines. The 681 is available in pressure ranges from 0 to 1 psi (50 psi over-pressure) up to 0 to 300 psi (1,000 psi over-pressure) and features a ±0.20% full-scale accuracy.

This Dwyer unit is fully sealed to withstand high pressure wash-down in Clean-in-Place (CIP) and Sterilize-in-Place (SIP) installations. Available as a 1-1/2 or 2 inch process connection, the 681 features a no liquid fill diaphragm with negligible clamping effect. A 1/2 inch conduit fitting, 15-foot (4.5m) shielded cable with vent tube and sealed screws for zero and span adjustment combine to make this Dwyer sanitary pressure transmitter completely watertight.
