Claims (3)

The object of the invention A sensor, in particular for control knots of metalworking machines, having a radius measuring lever raised by a compressed air device, characterized in that the measuring lever (4) is located on the axis (5) by sliding bearings or rolling bearings (6) in the housings (7) located in the housing (1), the measuring lever (4) being connected to the piston (15) of the compressed air cylinder (12) by means of the coupling element 14) in the housing (1) between the measuring transducer (5) and the bearing (6) ) and the stroke height of the measuring lever (4) by the coupling element (14) is regulated by the adjustment device (17) and the measuring lever (4) is led out of the hermetic body (1) via the seal (16), the opening (22) for the seal (16) being offset to the axis of the lever (4) which is in the measurement position. Sensor according to claim 1, characterized in that the measuring lever (4) with the axis (5) is arranged in the housing (1) by means of flanges (8) on the bearings (6), one of the bearings being prestressed by springs ( 10) and on the axis (5), torsion springs (11) are axially disposed, which are supported at one end by the measuring lever (4) and by the other end by cutouts in the housings (7) serving simultaneously to measure the torsional force. the springs (11), the measuring lever (4) being connected to the body (1) by tension springs (18, 19) acting in opposite directions, at which at least one of the tensioning springs (18, 19) is displaceable in the longitudinal direction by the control device (20) and above and below the measuring lever (4) there are zegulation stops (21) for defining the ranging of the lever (4) up and down. 5. Sensor according to claim 1, characterized in that, for raising the measuring lever (4) by the piston (15), the compressed-air cylinder (12) is positioned partially perpendicular to the measuring lever (4) in the housing (1), wherein the compressed-air inlet (15) ) is located in the body (1). Recognized by the invention on the basis of the results of the Expertise, carried out by the Office of Inventory and Patenting, Berlin, DD 2 drawings
