Dwyer DM-1103 DigiMag Digital Differential Pressure Gauge

Product Introduction

The Dwyer DM-1103 is a high-precision digital differential pressure gauge designed for measuring air and non-combustible gas pressures, replacing traditional analog Magnehelic® gauges with enhanced functionality. With a pressure range of 0–0.25" w.c. and ±1% FS accuracy (±2% for ranges ≤1" w.c.), it features a 4-digit LCD display for real-time readings in multiple units. The gauge supports field programming for pressure, air velocity, or flow modes and includes a filter maintenance alert (display blinking) when set thresholds are reached, making it ideal for critical environment monitoring.

Product Features

Accuracy & Stability:

±1% FS accuracy (at 32–122°F/0–50°C), ±2% for ultra-low ranges (≤1" w.c.).

±1% FS/year long-term stability with thermal compensation (±0.10% FS/°F for ≤1" w.c. ranges).

Display & Units:

4-digit LCD (0.60"H digits) with selectable update intervals (1 sec–10 min) or manual update.

Engineering units: in w.c., psi, kPa, mBar, mm Hg, etc., eliminating manual conversions.

Power & Versatility:

9V battery (150 hours @1 sec update) or 9–24 VDC external power (battery acts as backup).

Field-programmable for pressure, velocity, or flow (requires K-factor input for flow mode).

Alert & Safety Features:

Filter clogging alert (display blinking) at user-set thresholds.

NEMA 4X (IP66) enclosure for dust/water protection in harsh environments.

Construction & Materials:

Glass-filled plastic housing with stainless steel wetted parts (consult factory for details).

1/8" ID tubing connections for quick pressure port setup.
