Dwyer Series DM-2000 Differential Pressure Transmitter

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.

• 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.
• User-Friendly Design: Digital push-button zero/span calibration eliminates manual potentiometer adjustments. Optional 3.5-digit LCD (0.7" height) for real-time local readings in 4-6 engineering units.
• Durable Construction: Glass-filled plastic housing with 10 psig (0.69 bar) pressure limit. Operating temperature: 20-120°F (-6.67-48.9°C) for reliable performance in industrial environments.
• Flexible Installation: 1/8" ID tubing connections for quick pressure port setup. Vertical mounting orientation with integral bracket for easy integration.
