The
Series 681 Sanitary Pressure Transmitter is designed to
meet 3A standards for applications in food, dairy, beverage
and pharmaceutical processing, liquid level control, and sanitary
pipelines. The unit is fully sealed to withstand high pressure
washdown in Clean-in-Place (CIP) and Sterilize-in-Place (SIP)
installations. The Series 681 is designed with a unique, no
liquid fill diaphragm and a Tri-Clover sanitary pressure fitting
for easy installation with negligible clamping effect. A conduit
fitting, shielded cable with vent tube and sealed screws for
zero and span adjustment combine to make the Series 681 completely
watertight.
