MOISTURE DETECTION SYSTEM AND METHOD OF USING THEREOF Russian patent published in 2009 - IPC B60S1/08 G01F23/28 

FIELD: electricity.

SUBSTANCE: as per the first version, moisture detection system consists of an electric conductor, vibration generator that supplies the appropriate signal of the specified amplitude and frequency, resonance circuit, filtering circuit, and analogue-to-digital converter and controller. As per the second version, the system consists of the means located on a base and meant for passing electric current. That means responds to the signal supplied from vibration generator for feeding the resonance signal of the second amplitude the value of which depends on resonance frequency of the current-passing means. As per the third version, the system consists of a base, electric conductor located on that base, and detection means sensitive to vibration generator signal and electric conductor. As per the fourth version, the system includes liquid storage reservoir, electric conductor located on the above reservoir, the means sensitive to vibration generator signal and electric conductor. The means serves for supplying control signal when detecting such change of resonance frequency of electric conductor, which corresponds to the reservoir liquid level which is lower than the expected one. Moisture detection method provides the use of the base, excitation of electric conductor with vibration generator signal, determination of the first amplitude of electric conductor, determination of the second amplitude of electric conductor and determination of difference between the first and the second amplitudes.

EFFECT: improving operating reliability of moisture detection system.
