Description

Electronet Series DPT-225D are Differential Pressure Transmitters designed for fast, reliable, and maintenance-free operation. They are suitable for a wide range of industrial applications involving clear gases and liquids.
The transmitter provides electrical output in 4–20 mA DC or 0–5V DC, proportional to the input pressure. A PNP alarm output (100 mA max.) is also available.
All wetted parts are made of stainless steel and are hermetically welded for maximum durability.
