Patent number: 6606912Abstract: A construction for mounting a pressure detector prevents the detector diaphragm from being strained by stress applied to the pressure detector as the detector is mounted in a fixture main body provided in a pipe line or the like, thereby keeping the output characteristics and temperature characteristics of the detector from greatly differing before and after the mounting. The pressure detector is constructed by combining and fastening together a diaphragm base having a diaphragm and a sensor base having a sensor element therein that is activated by displacement of the diaphragm base. The pressure detector, with a gasket placed thereunder, is disposed in a mounting hole of a fixture main body that is mounted in a pipe line. The pressure detector is air-tightly pressed and fastened by a presser member inserted from above in the mounting hole.Type: GrantFiled: April 4, 2001Date of Patent: August 19, 2003Assignees: Fujikin Incorporated, Tokyo Electron LtdInventors: Tadahiro Ohmi, Takashi Hirose, Eiji Ideta, Nobukazu Ikeda, Ryousuke Dohi, Kouji Nishino, Kazuhiro Yoshikawa, Satoshi Kagatsume, Jun Hirose, Kazuo Fukasawa, Hiroshi Koizumi, Hideki Nagaoka
