PRESSURE SENSOR

摘要

PURPOSE: A pressure sensor adopting a strain gauge and electronic technology for the processing and amplifying of signal are provided to improve reliability and to make mass production by promoting packaging technology. CONSTITUTION: A pressure sensor(100) comprises a port type sensing part, a supporting ring(110), and a printed circuit board(122). The supporting ring comprises one or more mounting tabs. The sidewalls facing of the port type sensing part and supporting ring form the lap joint of the similar height. The printed circuit board comprises a plurality of contact pads. The contact pad is arranged in the inner side of the supporting ring and is attached to one or more mounting tabs.
