A new, patented technology (EMD technology) is used to create the electrical voltage from the applied torque.
The nickeliferous steel shaft is impregnated with a permanent magnetic pattern. Torque changes this pattern as well as the magnetic field.
As a result, the sensor delivers a torquedepending measurement signal for the evaluation by EMD electronic of the stator.
The function derives only from a magnetization of the shaft (no strain gauges, no wiring).
An ASIC for signal extension gives the user a torque-proportional electrical voltage.
