Abstract
A pressure sensor device includes a pressure sensor chip containing a diaphragm, piezo-resistors, an amplifying circuit and various kinds of adjusting circuits, and a base member to which the sensor chip is joined, with the diaphragm facing a through hole of the base member. The base member and a metallic member are joined so that their respective through holes communicate with each other. The metallic member is bonded to a resin case, and a signal terminal of the resin case and the pressure sensor chip are electrically connected to form a pressure sensor cell. With an O-ring attached to the metallic member and with the resin case pressed from above, the pressure sensor cell is secured to an enclosure, such as an oil enclosing block. Using a connector having a bending section and a threaded section, the pressure sensor cell can be secured to the connector by bending the bending section over the pressure sensor cell. The threaded section can be screwed into the enclosure.
