    • 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 airtightly pressed and fastened by a presser member inserted from above in the mounting hole. The presser member is brought in contact with a block upper surface of the diaphragm base, and the gasket is also brought in contact with the block lower surface of the diaphragm base. A shallow groove is defined in the form of a ring on the lower surface of the block at a place inward of the portion contacting the metal gasket so that the shallow groove absorbs strain caused by the presser member.
    • 用于安装压力检测器的结构防止检测器膜片由于施加到压力检测器的应力而受到应变,因为检测器安装在设置在管线等中的夹具主体中,从而保持检测器的输出特性和温度特性 探测器在安装之前和之后差别很大。 压力检测器通过将具有膜片的膜片基座和其中具有传感器元件的传感器基座组合并紧固在一起而构成,所述传感器基座通过膜片基座的位移而被激活。 压力检测器,在其下方放置有垫圈的压力检测器布置在安装在管线中的夹具主体的安装孔中。 压力检测器通过从上方插入安装孔的按压部件被气密地按压并紧固。 按压构件与膜片基座的块上表面接触,并且垫片也与膜片基座的块下表面接触。 在与金属垫片接触的部分的内侧的位置处,在块体的下表面上以环的形式限定浅槽,使得浅槽吸收由压紧构件引起的应变。 <图像>
