Description
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.
Viatran technology allows for accurate pressure measurement up to 1000 PSI. The transmitter also has no moving parts,
isolation diaphragm, or oil fill to contaminate your process fluid.
