Dwyer DXW-11-153-3

When you need trustworthy differential pressure monitoring across filters, fans, pumps or coils, the DXW‑11‑153‑3 offers a strong solution. Many installations suffer from switches that cannot handle outdoor conditions, high static pressure or fluid exposure—this model thrives under those challenges. Its wet/wet design measures two process pressures directly (rather than relying on air or vacuum references), making it ideal for monitoring filter difference, proving flow through chillers, or ensuring pump performance. The brass wetted connection and fluoroelastomer diaphragm tolerate a wide variety of gases and liquids. Featuring a weather‑proof NEMA 4X housing, the unit works gracefully in dusty, oily or wash‑down environments—superior to generic indoor switches. With an externally adjustable set‑point screw and removable terminal block, installation and maintenance are simpler and faster. Whether you’re retrofitting a facility, keeping maintenance labor down or specifying for new build automation, the DXW‑11‑153‑3 delivers professional performance and durability. Its combination of range, ruggedness and flexibility sets it above many basic differential pressure switches that offer narrower ranges or indoor‑only housings.
