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.
