Sensor includes electrically deformable measuring cell (2), which has mountings (5,6) and cross members (7) connected by elastic hinges (8). Deformation of cell is due to application of force to be measured. A digital system (3) is used to measure displacement representative of cell deformation, and generates digital signal corresponding to direct measurement of force applied. Digital system has a digital axis (12) and an incremental rule (13) fixed to the measuring cell by mounting (6) and a measuring head (14) is fixed on frame (9) of manipulator arm. Sensor is associated with a stop (15) for adjustment of stop position of the measuring cell at its null deformation point which corresponds to the absence of any applied force on cell. The stop is formed by an eccentric device (29) whose angular position is set by digital means. |
