Dwyer DM-1102 DigiMag Digital Differential Pressure Gauge
Product Introduction
The Dwyer DM-1102 is a precision digital differential pressure
gauge from the DM-1000 series, designed for monitoring air and
non-combustible gas pressures in critical environments like
hospitals, clean rooms, and temporary facilities. With ±1% FS
accuracy and a 4-digit LCD display, it replaces analog gauges with
digital reliability, offering selectable Imperial/Metric units and
field-programmable settings for pressure, air velocity, or flow.
Powered by a 9V battery or 9–24 VDC, it balances portability with
versatile deployment.
Product Features
Accuracy & Stability:
±1% FS accuracy (includes linearity) for precise measurements.
±1% FS/year long-term stability for consistent performance.
Display & Units:
4-digit LCD (0.60"H digits) with real-time readings in in w.c.,
kPa, mBar, etc.
No unit conversion needed; switch between metrics via button
controls.
Field Programmability:
Configure for pressure, air velocity, or flow (with K-factor input
for pitot tubes).
Set filter maintenance alerts via display flashing at pre-defined
thresholds.
Power Versatility:
9V battery (ideal for wireless setups) or 9–24 VDC (for permanent
installations).
Low power consumption (5 mA max.) extends battery life in field
use.
Durable Design:
Glass-filled plastic housing with NEMA 4X (IP66) rating for
dust/water protection.
Operating temp: 0–140°F (-18–60°C) suitable for diverse
environments.
