Piezoelectric pressure sensor e.g. water-cooled sensor, has piezoelectric measuring units arranged within pre-stressing units, which are arranged along sensor longitudinal axis, and pre-stressed between diaphragm and housing base

摘要

The sensor has piezoelectric measuring units (3) arranged in a housing (2) and pre-stressed between a diaphragm (4) and a housing base (5), where the diaphragm is laterally arranged at the housing. The piezoelectric measuring units are arranged within pre-stressing units (8), which are arranged along a sensor longitudinal axis (1`). The piezoelectric measuring units are designed as rectangular plates, and the pre-stressing units are arranged equidistantly between the piezoelectric measuring units.
