Abstract:
1. A sensor, comprising: a first electrically conductive element having a first diameter on a proximate portion of the first electrically conductive element and a second diameter on a distal portion of the first electrically conductive element, where the second diameter is smaller than the first diameter; a second electrically conductive element having a first diameter on a proximate portion of the second electrically conductive element and a second diameter on a distal portion of the second electrically conductive element, where the second diameter is smaller than the first diameter; an electrically insulative element connected to the first electrically conductive element and the second electrically conductive element, where the distal portion of the first electrically conductive element fits within a proximate end of the electrically insulative element, where the distal portion of the second electrically conductive element fits within a distal end of the electrically insulative element, and where the proximate portion of the first electrically conductive element and the proximate portion of the second electrically conductive element are located external to the electrically insulative element; and multiple electrically conductive weights located within a cavity of the sensor, wherein the cavity is defined by an interior surface of the first electrically conductive element, the electrically insulative element, and an interior surface of the second electrically conductive element.
