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.
Product Features
Precision Measurement:
±1% FS accuracy at 70°F with ±1% FS/year long-term stability.
Responds quickly to pressure changes for real-time alerts in
critical scenarios.
Signal Output & Compatibility:
4–20 mA output (2-wire) compatible with building automation
systems.
Same mounting dimensions as Magnehelic® gauges for drop-in
replacements.
User-Friendly Design:
Digital push-button zero/span calibration eliminates potentiometer
adjustments.
Optional 3.5-digit LCD (0.7" H) with field-selectable engineering
units (4–6 units depending on range).
Durable Construction:
Glass-filled plastic housing with 10 psig pressure limit (0.69
bar).
Operating temperature: 20–120°F (-6.67–48.9°C).
Installation Flexibility:
Vertical mounting with 1/8" ID tubing connections for quick
pressure port setup.
Tamper-proof button configuration prevents accidental setting
changes.
