space Product Description:

Designed for many markets/applications. The DPW version of Dylix’s differential pressure transmitter is designed for mechanical switch replacement where ruggedness and reliability are required at a competitive price. The DPW is 100% solid state with no moving parts and is ideal for high-cyclical applications.

Wide pressure ranges available. The DPW is available from 1” H2O through 5,000 psi through the use of Dylix’s DP or DPC Series pressure modules.

Manufactured for extended life cycle Dylix’s DPW is built using advanced manufacturing techniques to ensure symmetry between the Hi and Lo pressure ports. Symmetry, along with automated welded procedures and extreme environmental burn-in give Dylix’s differential pressure products excellent performance and reliability over time and at high elevated line pressure.

Solid-State Switch with optional analog output The DPW’s DPST switch is rated at 1 Amp @ 60 Vdc and is available in fixed or adjustable pressure settings. A 4-20 mAdc analog output proportional to pressure is optional.
