Description

Electronet Series DPT-22 are Digital Differential Pressure Transmitters designed for fast, accurate, and trouble-free operation.
These transmitters are suitable for a wide range of industrial applications involving clear gases and liquids.
The electrical output is 4–20 mA DC or 0–10 V, proportional to the input pressure.
All wetted parts are made from stainless steel and are hermetically welded for long service life.
