MODEL 350 PRESSURE TRANSMITTER

3A approved, Flush Machined Diaphragm Sensor, Tri-Clamp Fitting

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.

Features

Many Options available

All Stainless Steel construction

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.
