    Abstract: A remote wireless moisture sensing unit is insertable into soil. The sensing unit includes at least three capacitive sensors positioned at three spaced apart levels with respect to the surface of the soil. The capacitance of each sensor increases in the presence of increased moisture content of the soil proximate to the sensor. An analog multiplexer selectively routes each sensor to an input to a capacitively-controlled oscillator to cause the oscillator to generate a clock signal having a frequency responsive to the capacitance of the currently connected sensor and thus responsive to the moisture content proximate to the currently selected sensor. A processor generates a respective data value for the frequency corresponding to each sensor and transmits the data values for the sensors via a radio frequency transceiver. The data values are processed to determine the moisture content of the soil at the three sensor levels.

  • Publication number: 20140125361
    Abstract: A method and system for determining a distance from a probe to an object includes generating a first electric field by applying a first signal across a first pair of electrodes aligned along a first axis and generating a second electric field by applying a second signal across a second pair of electrodes aligned along a second axis substantially perpendicular to the first axis. After generating the signals, a first change in the first signal due to the object interacting with the first electric field and a second change in the second signal due to the object interacting with the second electric field is concurrently detected. A distance of the object from the first and second pair of electrodes can be calculated based on a ratio of the first and second changes.

    Abstract: A sensor for monitoring external loads acting on a pin assembly includes a pin having an axial interior bore defined therein and having a length defined from a first end to an opposed second end thereof. A core pin is mounted axially within the interior bore of the pin spaced radially inwardly from the interior bore for relative displacement with respect to the pin. A capacitor is provided having an inner capacitor plate mounted to the core pin, and an outer capacitor plate mounted to the pin, such that relative displacement of the core and the pin due to external loading on the pin results in relative displacement of the inner and outer capacitor plates. The capacitor is configured and adapted to be connected to an electrical circuit to produce signals indicative of external loading on the pin based on relative displacement of the inner and outer capacitor plates.

  • Patent number: 8610591
    Abstract: The invention inter alia relates to a method for monitoring the bearing current of an electrical machine (10). An electrode (100) arranged at a distance (d) to a shaft and the shaft—due to the gap (S) between the electrode and the shaft—produce a measurement capacitance (C) and an electric shift current (i) which flows through the measurement capacitance when there is a temporal change of the voltage (Ug) applied between the shaft and the housing is measured. A measurement signal (Ms) indicating a bearing current flow is generated when the shift current or a measurement variable produced by the shift current meets a predetermined trigger criterion. Preferably, the electrode has a circular inner contour so that the gap is annular. The annular inner contour results in an error compensation in the case of a balance error of the shaft because the factor dC/dt remains at least substantially constant. Due to the contactless measurement of the shift current, no contact brushes for contacting the shaft are required.
