Model A5 Pressure Transducer

Absolute pressure
Gauge pressure
Stainless steel
High Range
Infinite resolution

This type of sensor measures the pressure of a compatible fluid or gas. This unit has both gauge pressure and absolute pressure versions.

A gauge pressure transducer measures with respect to atmospheric pressure. An absolute pressure transducer measures with respect to a vacuum.
