Calibration machine for weight transponder
To accurately measure the weight of products moving on a conveyor belt, a client of Huygens Engineers uses a belt with sensors: small measuring cells with double membranes, whose degree of deflection is related to the weight placed on them. We developed a machine that determines the deflection of the membranes for a baseline series and simultaneously carries out fatigue tests. With this machine, the client can determine when the sensors require recalibration and easily perform this calibration. To develop this machine, we simulated the deformation of the membrane for a large number of cases of dimensional deviations and loads and compared this with actual measurements. By using these simulations to construct an FEM model, we were able to determine the behaviour of the membranes. This ensures that the calibration machine accurately measures the sensors and can ac-curately validate the durability.
