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.
