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.
Product Features
Accuracy & Stability:
±1% FS accuracy at 70°F (21°C) with ±1% FS/year long-term stability.
Thermal effect: ±0.055% FS/°F (0.099% FS/°C) for consistent readings across temperatures.
Signal Output & Compatibility:
4–20 mA output (2-wire) with loop resistance up to 1250 Ω.
Direct replacement for Magnehelic® gauges, reducing installation time.
