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.
