Dwyer Series DM-2000 Differential Pressure Transmitter for Air & Gases

Dwyer Series DM-2000 Differential Pressure Transmitter for Air & Gases

Product Introduction

The Dwyer Series DM-2000 Differential Pressure Transmitter is engineered to measure air and compatible gas pressures, delivering a standard 4-20 mA output signal for seamless integration with industrial control systems. Its housing is designed to fit the same cutout as a standard Magnehelic gauge, enabling straightforward retrofitting. Factory-calibrated for specific pressure ranges, this transmitter features glass-filled plastic construction with integrated pressure connections for quick installation. Digital push-button zero and span adjustments simplify field calibration, while an optional 3.5-digit LCD displays process values in selectable engineering units, making it ideal for HVAC, cleanroom, and industrial monitoring applications.

Key Features

Magnehelic -Compatible Mounting

Direct replacement for standard Magnehelic gauges, using identical cutout dimensions for easy retrofit.

Reliable Pressure Sensing

Measures air and non-combustible gases with ±1% F.S. accuracy at 70°F.

Stable performance with ±1% F.S. drift per year.

User-Friendly Calibration

Digital push-button zero/span adjustments replace traditional potentiometers for precision tuning.

Field-selectable engineering units (4-6 options) via single button.

Optional Visual Display

3.5-digit LCD (0.7" height) shows real-time pressure values in psi, inH₂O, mmH₂O, kPa, mbar, or Pa.

Robust Construction

Glass-filled plastic housing with integrated 1/8" I.D. tubing connections for durability.

Withstands 10 psig (0.69 bar) pressure limits and -6.67°C to 48.9°C operating temperatures.

Industrial Compatibility

2-wire 10-35 VDC power supply with 4-20 mA output, supporting up to 1250 ohm loop resistance.

Screw-type terminal block for secure electrical connections.

The Dwyer Series DM2000 Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM2000 housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic® gage. A wide range of models are available factory calibrated to specific ranges.

Pressure connections are inherent to the glass filled plastic molded housing making installation quick and easy. Digital push-button zero and span simplify calibration over typical turn-potentiometers. An optional 3.5 digit LCD shows process and engineering units. A single bush button allows field selection of 4 to 6 engineering units depending on range.
