MULTICHANNEL DEVICE FOR BULK SOLIDS MOISTURE MEASUREMENT Russian patent published in 2018 - IPC G01N25/56 

FIELD: measuring devices.

SUBSTANCE: device refers to the measuring one, in particular to technical means for measuring the grain moisture during drying and storage. Essence of the claimed device is, that a multichannel moisture measuring device for bulk materials contains a power supply, a comparator, an RS flip-flop, a key, sensors, an exemplary capacitor, a clock generator, a multiplexer, a channel number counter, channel number indicator, the reference frequency generator, the first and second “I” elements, the moisture meter, the calibrator, the moisture indicator, the reference voltage is applied to the direct input of the comparator from the power supply at a time, and the operating voltage is applied to the key input, the control input of which is connected to the inverse output of the RS flip-flop and the second input of the second “I” element, while the output through the exemplary capacitor with the common bus; the sensor inputs are connected to the comparator's inverse input and the key output, the outputs through the multiplexer with the common bus; the R input of the flip-flop is connected to the output of the comparator, and the S input - with the clock generator output, the second input of the moisture meter and the input of the channel number counter, the output of which is connected to the control input of the multiplexer and the input of the channel number indicator; the direct flip-flop output is connected to the second input of the first “I” element, the first input of which is connected to the output of the reference frequency generator, and the output with the first input of the moisture meter, the output of which is connected to the first input of the second "I" element, while its output through the calibrator is connected to the input of the humidity indicator.

EFFECT: technical result observed in the implementation of the claimed device consists in increasing the accuracy of measurements, simplifying the device and its operation, shortening the measurement time, expanding the functionality of the device.
