Abstract

A multiaxial force/torque sensor assembly and method for assembling such a sensor assembly are disclosed. The sensor assembly includes a set of at least two sensors each being made of strain gauges, which are each arranged at a definite angle and distance relative to each other and which are each fixed to a transducer body, which is mechanical contact with a printed circuit board. The printed circuit board includes clearances for each strain gauge as well as associated electronic components and wiring located on the remaining area of the printed circuit board which will monitor compressive and tensile stresses in the measurement directions of the sensors. The method includes positioning the strain gauges on the plane measurement surface of a transducer body in a definite arrangement; fixing the strain gauges to the transducer body by means of adhesives, and connecting the strain gauges to respective conductors by means of electrically bonding.
