This potentiometer comprises differential MR, driven by a magnet with no amplifier. At
the output, the resistance change can be used as a signal. On applying the operating
voltage a sinusoidal voltage results at the output, which is not temperature-
compensated. With the aid of external circuitry this signal can be amplified, temperature-
compensated and adapted for various applications.
