Sensor for levels of conductive liquids |
摘要 |
A liquid level sensor comprises a plurality of electrodes arranged in a defined relationship with respect to a container filling trajectory, a signal generator coupled to one or more of the plurality of electrodes, a signal receiver coupled to one or more of the plurality of electrodes, and a sensing circuit coupled to at least one of the signal generator and signal receiver. The sensing circuit is configured to produce an output indicative of electrical resistance between at least one pair of the plurality of electrodes. The sensing circuit may be associated with the signal receiver and/or with the signal generator.
