Dwyer RSM-5-B Room Status Digital Pressure Gauge
Product Introduction
The Dwyer RSM-5-B Room Status Digital Pressure Gauge is a
high-accuracy instrument designed for critical low differential
pressure monitoring in environments requiring strict safety and
compliance. With a measurement range of ±1" w.c., this gauge is
ideal for hospital isolation wards, pharmaceutical facilities, and
clean rooms, adhering to CDC guidelines for pressure control. It
features a graphic user interface for intuitive access to pressure
data, calibration settings, and alarm configurations, housed in a
NEMA 1 (IP20) fire-retardant plastic enclosure for indoor use. The
RSM-5-B supports selectable output signals (4–20 mA, 0–5 VDC, 0–10
VDC) and optional BACnet communication for seamless integration
with building automation systems.
