Dwyer 605-10C Magnehelic Differential Pressure Indicating Transmitter 0-10 In WC

Dwyer 605-10C Magnehelic Differential Pressure Indicating Transmitter 0-10 In WC

The Dwyer 605-10C is a Magnehelic Differential Pressure Indicating Transmitter combining an analog dial gauge with a 4–20 mA electrical output signal in a single instrument. It measures differential pressure in the 0–10 inches of water column range and simultaneously provides a proportional current output for remote monitoring or control systems. Dwyer's Magnehelic series is one of the most widely recognized lines of differential pressure gauges in industrial and commercial use.

Applications

The Dwyer Magnehelic series has been a standard instrument in HVAC, cleanroom, and industrial process applications for decades and remains widely used today. The 605 series adds a 4–20 mA transmitter output to the classic Magnehelic dial, making it suitable for building automation systems, filter differential pressure monitoring, air handler performance tracking, fume hood face-velocity control, and any application requiring both a local visual indication and a remote analog signal. These instruments are commonly found in pharmaceutical manufacturing, hospital HVAC systems, semiconductor cleanrooms, and general industrial air-handling installations where differential pressure across filters, dampers, or ductwork must be monitored continuously. The 0–10 in WC range of the 605-10C is a common span for medium-resistance HVAC filter banks and cleanroom pressure differentials.
