Dwyer Instruments DM-002 DigiMag Differential Pressure Transmitter 0-0.25"WC

The Dwyer Instruments DM-002 DigiMag Differential Pressure Transmitter is a precision instrument designed to sense the pressure of air and compatible gases and transmit a standard 4-20 mA output signal. This versatile transmitter features a 3.5-digit LCD display that shows process values and engineering units, making it ideal for HVAC, cleanroom, and industrial monitoring applications.

Key Features:

• Pressure range: 0 to 0.25 inches water column (WC)
• 4-20 mA DC output signal for integration with control systems
• Accuracy: ±1-2% of full scale
• Digital push-button zero and span calibration for easy field setup
• Field-selectable engineering units via single push-button
• Power requirement: 10 to 35V DC, 2-wire connection
• Process connections: 1/4" hose barb fittings integral to housing
• Screw terminal electrical connections
• 10 psi overpressure rating for reliability
• IP66/NEMA 4X environmental rating for indoor/outdoor use

The DM-002 housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic gauge (4.75" diameter), making it perfect for upgrading existing installations without modifying panel cutouts. The glass-filled plastic molded housing with integral pressure connections reduces installation time and complexity. Compatible with air and non-combustible gases, this transmitter is suitable for pressure, flow, and velocity monitoring applications.
