Abstract
The invention relates to a measuring sensor (,), comprising: detector legs (,movable to varying distances (H,. . . H,) from each other; detector elements (,) and possible emission elements (,) in the detector legs; pivoting means, the detector legs being tiltable (M) relative to each other around a pivoting axis (,) established thereby; operating legs (,), each of which is attached to done detector leg and serves as an extension thereof; a spring element (,) between the operating legs for producing a compressive force (P,) between the detector legs, containing for example a finger which is non-invasively measured with the measuring sensor for some characteristic. The spring element (,) consists of an elastomer material and a solid component, extending from the first operating leg (,) to the second operating leg (,). In addition, the spring element is in gripping contact with both operating legs (,and,) over such a length (L,) which is located substantially within a total length (L,) between the surrounding of said axis line (,) and outer ends (,) of the operating legs.
