Sanitary pressure transmitters

Model 350 Pressure Transmitter

Model 350 Pressure Transmitter

A flush diaphragm inhibits bacterial growth and facilitates Clean in Place (CIP) systems. The quick-disconnect Tri-clamp connections make these transmitters ideal for pharmaceutical, dairy and food processing applications where frequent cleaning is required.
