Dwyer DM-2000 Series Differential Pressure Transmitter

Dwyer DM-2000 Series Differential Pressure Transmitter 

Product Introduction

The Dwyer DM-2000 Series Differential Pressure Transmitter is engineered to monitor pressure for air and compatible gases, delivering a standard 4–20 mA output signal for seamless integration with industrial control systems. Its housing is precision-designed to fit the same diameter cutout as the standard Magnehelic® gauge, enabling effortless replacement and system upgrades. Factory-calibrated across a wide range of pressure spans—including models with optional 3.5-digit LCD displays—the transmitter combines quick response times with user-friendly digital push-button zero and span adjustments, eliminating the need for traditional potentiometer calibrations. The glass-filled plastic molded housing incorporates inherent pressure connections for rapid installation, while field-selectable engineering units (4–6 options, depending on range) enhance versatility for diverse applications.
