The Ashcroft GC55 wet/wet differential pressure transducer is a compact, high-differential pressure transducer ideal for filter monitoring, HVAC hydronic cooling and heating systems, and pump controls. A three wire 4 to 20mA or 1-5VDC output signal connects the transducer to external controls or data acquisition.

Ashcroft GC55 wet/wet differential pressure transducers contain two polysilicon thin film sensors with welded, stainless steel, wetted components to accommodate wet or dry pressure media up to 300 psid. A robust, cast aluminum housing features a bright LED front-panel display for local indication and switch status along with a button to allow the user to select between the dP value and the line pressure reading from either sensor. The user also has the ability to re-range the transducer and set trip points for the on-board switch contacts.
