    • The joint comprises a first joint component (1) having axial aperture and a second joint component (4) having an axial aperture arranged coaxially with the aperture in the first joint component. Joint components (1) and (2) have a gasket ring (7) interposed therebetween to act as a fluid seal. The components are jointed by bolts (10); within the gasket are a number of stress or strain responsive elements equispaced around the entire periphery of the gasket, each comprising a pair of electrodes sandwiching a stress or strain responsive material. The responsive elements have opposed faces which are spaced from the opposed faces of the gasket and the electrodes and are connected to an output via leads (18, 19) to give an indication of the stress or strain within each individual element corresponding to the torque force applied to a proximate bolt.
    • 接头包括具有轴向孔的第一接头部件(1)和具有与第一接头部件中的孔同轴布置的轴向孔的第二接头部件(4)。 接头部件(1)和(2)之间具有垫圈环(7)以用作流体密封。 组件通过螺栓(10)连接; 垫圈内的是多个应力或应变响应元件围绕垫圈的整个周边等间隔,每个包括一对电极,夹持应力或应变响应材料。 响应元件具有与垫圈和电极的相对面间隔开的相对面,并且经由引线(18,19)连接到输出端,以给出对应于扭矩力的每个单独元件内的应力或应变的指示 应用于近似螺栓。
