Model G2 Pressure Transducer

Brand: Ashcroft Inc
Does not ship to Virginia, United States

The Ashcroft Type G2 Pressure Transducer has been specifically designed with the high volume OEM in mind.

A ±1% Total Error Band accuracy is accomplished by marrying a high performance ASIC to a very stable, field proven polysilicon thin film pressure sensor.

The sensor is electron beam welded to a pressure fitting of stainless steel, which provides excellent overpressure capability and outstanding durability in the presence of shock and vibration.

The circuitry is held within an internal cage and housed in an enclosure of reinforced Nylon.
