Model 440 Pressure Transducer/Transmitter

Absolute pressure
Gauge pressure
High resolution
4-20mA output
High accuracy
Stainless steel



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.
