Title: DETERMINING DEVICE FOR DETERMINING A VALUE REPRESENTING A DOSE OF A DOSE METERING DEVICE, AND A METHOD FOR OPERATING SAME
Abstract:
The invention relates to a determining device (100) for determining a value (114) which represents a dose of a dose metering device (102). The determining device (100) comprises an eddy current based rotation-angle sensor (108) that can be coupled to a rotatable dose metering head (104) of said dose metering device (102), and an evaluation unit (110). The rotation-angle sensor (108) is designed to image, in a rotation-angle signal (112), a dose metering head (104) angle of rotation (606) which represents the dose. The evaluation unit (110) is designed to determine the value (114) of the dose on the basis of said rotation-angle signal (112).
