Abstract: The present invention relates to a wireless sensor for controlling the tension of traction cables, formed by a body (1) provided at the ends and in the central area with conformations (2, 3 and 4) which determine opposing support points on the cables of application, an electronic module (6) which converts the bending deformations of said body (1) into equivalent tension data of the cables on which the sensor is applied, a memory module (9) which stores the data provided by said electronic module (6) and an emitter module (10) which allows transmitting those data provided by the electronic module (6) wirelessly through an antenna (12), all being housed in the body (1).

Abstract: Measuring instrument for hanging masses for machines which operate with traction cables, including a body (1) in which some extreme stops (2) are incorporated to support the cables (9) of application, having in the central area a cable (9) pressure element (6), made up of a cylinder which is held on a support (4) with inclusion of some cylindrical washers (8) that can be substituted, by means of which a selective separation of the cylinder (6) is established respect to the body (1) for the passage of the cables (9) of application.
