DIELECTRIC MOISTURE METER Russian patent published in 2005 - IPC

FIELD: measuring engineering.

SUBSTANCE: dielectric moisture meter comprises two frequency dividers, recording pulse generators, and AND/OR elements. The output of the reference generator is connected with the first input of the AND/OR element, input of the recording pulse generator, and input of the first frequency divider. The first output of the first divider is connected with the input of the pulse generator. The second output is connected with the second input of the AND/OR element through the phase frequency self-adjusting unit, automatic controllable generator and second frequency divider and input of the recording pulse generator. The first output of the pulse recording generator is connected to the input of the digital voltmeter through the cadence input of the pulse generator. The output of the subtracting device is connected with the second output. The cadence output of the subtracting device of scaling is connected with the outputs of the digital voltmeter through the subtracting device. The cadence input of the subtracting device is connected with the output of the AND/NOT element. The outputs of the scaling device are connected with the inputs of the digital voltmeter through subtracting device.

EFFECT: enhanced accuracy.
