Abstract: The position transducer uses an elongated resistance which can be switched to a fixed voltage source to provide a voltage gradient along the resistance. A metal strip with a single aperture is arranged to be moved along parallel to the resistance and another elongated metal conductor is positioned on the other side of the metal strip so that the metal strip with the aperture is sandwiched between the resistance and the conductor. Physical movement of the strip moves the aperture and thus will change the voltage value electrostatically coupled from the voltage on the resistance to the conductor. An analog voltage constituting a function of a digital count value is repetitively switched onto the entire resistance and compared with this voltage value at a given high frequency. If the analog voltage is less than the voltage value on the resistance opposite the aperture, an up count signal is generated to increase the digital count and thus increase the analog voltage.
