Differential pressure sensor USD50B
For accurate measurements and differential pressure monitoring
The differential pressure sensors USD50B with piezoresistive sensor and welded metal diaphragm are typically used in process and environmental industries. Applications are level, volume, or mass measurements in liquids or gases, differential pressure monitoring, e.g. filters and pumps, and flow measurement (volume or mass flow).
