Pressure Transmitter vs. Pressure Transducer

Pressure transducers and pressure transmitters both measure pressure and convert it into an electrical signal. In many industrial settings, the broader term pressure sensor is also used to describe either type of device.

A Pressure transmitter includes built-in amplification and signal conditioning, then outputs a standardized signal such as 4–20 mA or 0–10 VDC. This makes transmitters better suited for longer cable runs, greater distance, and better noise immunity.

A Pressure transducer outputs a lower-level signal, such as mV/V, and is often used where signal conditioning already exists or cable runs are short.
