<p>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.</p> |
