Dwyer Series DM-2000 Differential Pressure Transmitter for Air &
Gases
Product Introduction
The Dwyer Series DM-2000 Differential Pressure Transmitter is a
versatile industrial device designed to measure pressure for air
and compatible gases, delivering a standard 4-20 mA output signal
for reliable process control. Engineered with a glass-filled
plastic molded housing, it fits seamlessly into the same diameter
cutout as a standard Magnehelic gage, ensuring easy retrofitting
and installation. Factory-calibrated for specific pressure ranges,
the DM-2000 combines precision with user-friendly functionality,
making it ideal for applications requiring accurate differential
pressure monitoring.
Product Features
Accurate Pressure Sensing:
Measures pressure of air and non-combustible, compatible gases with
±1% FS accuracy (±4% FS for ±30 Pa model) at 70°F.
Stable performance with ±1% FS/year drift resistance.
Easy Installation & Compatibility:
Housing designed to match standard Magnehelic gage cutout
dimensions for straightforward mounting.
Inherent pressure connections in the molded housing simplify setup
with 1/8" I.D. tubing.
Digital Calibration & Display:
Digital push-button zero and span adjustments replace traditional
potentiometers for intuitive calibration.
Optional 3.5-digit LCD (0.7" height) displays process values in 4-6
selectable engineering units via a single button.
Reliable Performance Specifications:
Temperature range: 20 to 120°F (-6.67 to 48.9°C); pressure limit:
10 psig (0.69 bar).
Thermal effect: ±0.055% FS/°F (standard) or ±0.13% FS/°F (±30 Pa
model).
Electrical & Connectivity:
2-wire 10-35 VDC power supply with 4-20 mA output; loop resistance
up to 1250 Ω.
Screw-type terminal block for secure electrical connections;
vertical mounting orientation.
Compact & Lightweight:
Weighs only 4.8 oz (136 g), suitable for space-constrained
installations.
