HTS-B19 QUP-A High Accuracy Quartz Crystal Pressure Transducer

The HTS-B19 QUP-A quartz crystal pressure transducer resourced by Hitech Sensors is designed for demanding pressure measurement applications requiring exceptional accuracy, repeatability and long-term stability.

Product Detail
The HTS-B19 QUP-A quartz crystal pressure transducer resourced by Hitech Sensors is designed for demanding pressure measurement applications requiring exceptional accuracy, repeatability and long-term stability.

The sensor combines advanced quartz crystal technology with high strength nickel-based superalloys. The pressure housing is manufactured from Inconel 718 and the pressure isolation structure uses an Inconel 625 cone sealing design, providing outstanding resistance to corrosion, pressure and temperature extremes.


Features:
