摘要： An electromechanical, fill-level, measuring device, comprising: a float, an outer drum with an outer ring of magnets, an inner drum with an inner ring of magnets, electromagnetic measuring elements, a measuring shaft with, and a servomotor with an drive shaft. The drive shaft is coupled with the measuring shaft via a transmission, wherein the servomotor rotates the measuring shaft via the transmission as a function of a control signal ascertained from the difference value of the measuring elements, so that, by relative movement between the outer and inner drums produced by a change of the liquid level to be measured, the difference value is returned to zero and from the rotation of the measuring shaft the current fill level measured value is ascertained. Sensor electronics is arranged on the measuring shaft within the inner drum, and radial, rotary transformer is embodied on the measuring shaft for transmitting at least the control signals from the sensor electronics to the main electronics and supplying for at least the sensor electronics with energy.
