The invention relates to a measuring sensor (1) for measuring positive and negative elongations on cylindrical or profiled bodies (6). The measuring sensor (1) consists of more than two parts and is essentially annular and has at least one tensioning element (7, 15). Two segments (2, 3) that can be tensioned are provided with a recess on the longitudinal center on the internal contour (22), the recess being disposed opposite the direction of tensioning (S) and accommodating a protruding elastic element (8) with a measuring element (10). The recesses can be pressed non-positively onto the surface of the body (6). The segments (2, 3) of the multi-part measuring sensor (1) that are diagonally opposite can be tensioned with their both ends by means of exchangeable and/or adjustable lateral guide members (4, 5, 26, 38) for the body to be measured (6).
Transducer (1) for electrical measurement of positive and negative extensions on cylindrical or profiled bodies (6), the transducer comprising more than two pieces and being substantially annular, with at least one clamping element (7, 15), where two clampable segments (2, 3) each have, in their longitudinal centre on the inner contour (22) and lying opposite each other in the clamping direction (S), a recess for a protruding resilient part (8) with a measurement element (10) which is pressed by force onto the surface of the body (6), characterized in that diagonally opposed clampable segments (2, 3) of the transducer (1) are clamped at both ends with at least one of interchangeable and adjustable side guide elements (4, 5, 26, 38) for the body (6) to be measured, wherein the segments (2, 3) are formed in yoke form, round or with multiple edges, which approximate to the form and size of the surface (13) of the body (6) but lie on this body (6) only in the area of the measurement element (10), where the faces (19) of the segments (2, 3) have a spacing (a) of at least 30% of the spacing (b) of the measurement elements (10).
