Dwyer DM-2000 Differential Pressure Transmitter 4-20 mA Output

Dwyer Series DM-2000 Differential Pressure Transmitter

Product Introduction

The Dwyer DM-2000 Series Differential Pressure Transmitter is a high-precision instrument designed to measure pressure differences in air and non-combustible gases, outputting a standard 4–20 mA signal for seamless integration with industrial control systems. Engineered with a glass-filled plastic housing, it shares identical mounting dimensions with the standard Magnehelic® gauge, enabling straightforward field upgrades. The transmitter features digital push-button zero and span adjustments for easy calibration, optional 3.5-digit LCD display, and field-selectable engineering units, making it ideal for filter monitoring, fan pressure analysis, and building static pressure control.
