space Product Description:
 

Designed for mechanical switch replacement. The GPW version of Dylix’s gage (or absolute) pressure transmitter is designed for mechanical switch replacement where ruggedness and reliability are required at a competitive price. The GPW is 100% solid state with no moving parts and is ideal for high-cyclical applications.

Wide pressure ranges available. The GPW is available from 2 psi through 100,000 psi through the use of Dylix’s BR, GX, GXR, or MR Series pressure modules.

Manufactured for low-cost of ownership Dylix’s GPW is built using advanced manufacturing techniques , along with automated welding procedures and extreme environmental burn-in to ensure excellent performance and reliability over time.

Solid-State Switch with optional analog output. The GPW’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 option
