| 摘要 |
The invention relates to a sensor for measuring mechanical stress which can be adapted to cables with different gauges, made up of a body (2) with a machined area (3) for a strain gauge and three pivots - an upper (4), a lower (5) and a central (6) pivot - which are distributed on the front surface (2a), the upper pivot (4) being stationary and the lower pivot (5) being retractable, which has a central pivot (6) attached to the body (2) via a movable attachment which, in a mechanical manner, enables horizontal movement thereof towards either side of the body (2), adapting to the gauge of the cable. The movable attachment is an attachment plate (9) to which the central pivot (6) is connected by a thread inserted on a screw (10), provided at the centre of the body (2), in a recess (11) having front and rear openings. The screw (10) passes through the body (2) from side to side in the recess (11) and is attached by a nut (12). |
