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.
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.
