Dwyer DM-2000 Series Differential Pressure Transmitter with Digital
Display
Product Introduction
The Dwyer DM-2000 Series Differential Pressure Transmitter with
Digital Display is a versatile instrument designed to monitor
differential pressure for air and compatible gases, outputting a
standard 4–20 mA signal. Engineered to match the mounting hole
dimensions of the 2000 Series Magnehelic® differential pressure
gauge, it enables seamless replacement and system upgrades. With a
range of pre-set pressure spans and customizable options for
special ranges, the transmitter caters to diverse industrial needs.
Its FRP-molded pressure joints and housing ensure easy
installation, while digital push-button controls simplify zero and
span calibration. The optional 3.5-digit LCD display provides
real-time on-site readings, with 4–6 selectable engineering units
tailored to different pressure ranges.
