Dwyer Series 2000 Magnehelic Differential Pressure Gauge (0–15 cm
w.c.)
Product Introduction
Product Introduction
The Dwyer Series 2000 Magnehelic Differential Pressure Gauge (0–15
cm water column) is a precision analog instrument designed to
measure pressure differences in low- to medium-pressure systems.
Engineered with a rugged die-cast aluminum housing, it delivers ±2%
full-scale accuracy for reliable monitoring of air and
non-corrosive gas pressures. The gauge’s patented bellows sensing
mechanism ensures quick response to pressure changes, while its
clear dial and durable construction make it ideal for industrial
applications such as filter monitoring, HVAC systems, and airflow
management.
Product Features
Accurate Pressure Measurement:
0–15 cm w.c. range with ±2% full-scale accuracy at 70°F (21.1°C).
Clear analog dial with undistorted plastic face for easy reading
from a distance.
Rugged Construction:
Die-cast aluminum case and bezel with acrylic cover, coated gray to
withstand 168-hour salt spray tests.
IP67 enclosure rating for protection against dust and water
immersion.
Quick Response Design:
Patented bellows sensing elements provide immediate reaction to
pressure changes, eliminating assessment delays.
Versatile Installation:
1/8 NPT female process connections for easy integration into pipe
systems.
Mounting orientation: diaphragm in vertical position (other
orientations available on request).
Wide Operational Range:
Temperature tolerance: 20–140°F (-6.67–60°C); optional
low-temperature model for -20°F (-28°C).
Pressure limits: -20 in Hg to 15 psig (-0.677 to 1.034 bar); MP/HP
options for higher pressure ratings.
Low Maintenance:
Relief plug activates at ~25 psig (1.72 bar) to protect against
overpressure.
Long service life with minimal downtime due to high-quality
components.
