发明名称 Variable fluid and tilt level sensing probe system
摘要 Digital tilt level sensing probe system comprising a set of multiple capacitor elements in a fluid container arranged along an axis of measurement where each multiple capacitor element represents a discrete level increment in dielectric material fluid to be measured. Individual capacitors in each element are horizontally spaced to reflect a level differential upon tilting of the fluid container from its normal attitude. In the case of a probe for sensing tilting in a single plane, a one-piece body is employed to include integral capacitor elements, mounting pad, connector, custom IC pad, and circuitry molded into such body. Alternative references may be employed for comparison with each capacitor assigned a unique time slot in a switching sequence.
