  • Publication number: 20210304927
    Abstract: A single turn potentiometer sensor has a substrate, a first and a second carbon print. The first carbon print, with a desired width, extends across a large circumferential angle. Ends of the carbon print are connected to a regulated power supply and ground. The second carbon print, with a width smaller than the first carbon print, surrounds a hole in the substrate and is positioned inside the first carbon print. The second carbon print provides a sensor output. A wiper contacts between the first and second carbon prints. A voltage divider changes value based on a wiper position on the first carbon print. One or more pads are positioned on the first carbon print. The one or more pads provides an input voltage to the sensor.
