Differential pressure sensor USD70

For low measuring ranges with very high overload resistance

The USD70 differential pressure sensors provide precise measurements in small measuring ranges – with high overload resistance. The piezoresistive sensors with welded metal diaphragm are typically used in process and environmental industries. Applications include level, volume, or mass measurements in liquids or gases, differential pressure monitoring, e.g. of filters and pumps, and flow measurements (volume or mass flow).
