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

Dwyer DM-2000 Series Digital Differential Pressure Transmitter

Product Introduction

The Dwyer DM-2000 Series Digital Differential Pressure Transmitter is engineered to measure pressure differences in air and non-combustible gases, outputting a standard 4–20 mA signal for seamless integration with industrial control systems. With a pressure range of 0–1250 Pa and ±1% FS accuracy at 70°F, it ensures precise monitoring for filter differential pressure, fan control, and building static pressure applications. The transmitter features a glass-filled plastic housing compatible with standard Magnehelic® gauge mounting dimensions, enabling easy field upgrades. Digital push-button zero/span adjustments and an optional 3.5-digit LCD display enhance usability, while its rugged design withstands 10 psig operating pressure for reliable performance.
