Dwyer Instruments 4002-2 Differential Pressure Gauge

Dwyer Instruments 4002-2 Differential Pressure Gauge is a differential pressure gage from DWYER's 4002 series. The provided description labels it as a CAPSUHELIC differential pressure gage and lists references such as EN F579, 7958 P, and EB, indicating its labeling and place within the product line. As a differential pressure instrument, it senses pressure difference and translates that difference into a readable indication on the gauge face, enabling quick assessment of system balance, flow conditions, or filtration status. The 4002-2 designation ties this unit to a family of gauges designed for reliability in pressure measurement, and the capsule-associated descriptor suggests a particular sensing mechanism within the instrument. The inclusion of these specific terms helps identify the device within DWYER's documentation and cataloging while clearly establishing its role as a differential pressure gauge rather than a single-pressure gauge or another instrument.
