Multi-component load indicator, for measuring up to three orthogonal force and torque components

The load indicator It comprises a first part (1) to which power is applied, and a second part (2) fastened to a fixture device. Between the first and second parts is a measurement zone (3) incorporating one or more measurement components (4,which measure force and torque components. The first and second parts are, mainly with the help of spark processing, produced from one piece as a piston (8) in a hollow cylinder (9), whereby the piston can be the first part and the hollow cylinder the second part, or vice versa. The parts are connected at least at two different points along the load indicator symmetry axis direction, which coincides with the direction of the first force component, with flat springs (11) which extend more in the load indicator peripheral direction than in a radial direction.
