Features

All Stainless Steel construction
Low Pressure Applications


Product Selection


The 346 pressure transducer meets the requirements for engine test stands and environmental test chambers where extremely accurate baraometric readings are crucial. It is also used in altitude test chambers where it an be scaled to a digital indicator to the pressure or equivalent altitude.

The high accuracy makes it ideal for use in Automated Weather Observation Systems (AWOS) and Automated Surface Observing Systems (ASOS) at airports.
