The Model GC55 is a compact wet/wet high differential pressure transducer, ideal for filter monitoring, HVAC hydronic cooling and heating systems, and pump controls, said the company. It contains two polysilicon thin film sensors with welded stainless steel wetted components to accommodate wet or dry pressure media up to 300 psid. A three-wire 4-20mA or 1-5 vdc output signal connects the transducer to external controls or data acquisition. A robust cast aluminum housing features a bright LED front panel display for local indication, along with a button to allow the user to select between the dew point value and the line pressure readings from either sensor. The user also has the ability to re-range the transducer and set trip points for the onboard switch contacts.
