MICROCONTROLLER DEVICE FOR CAPACITY AND RESISTANCE MEASUREMENT Russian patent published in 2010 - IPC G01R27/26 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment, in particular - to devices for measurement of capacity and active resistance. The measurement transducer of capacity and resistance into a binary code contains a microcontroller, a reference resistor, a capacity sensor, a reference capacity capacitor and the measured resistance resistor. The first outputs of the resistors of the reference and measured resistance are connected to the first plates of the capacity sensor and the reference capacity capacitor accordingly. Additionally introduced into the measurement transducer is a resistive voltage divider. The fist and second outputs of the voltage divider resistors are connected to the first input of the microcontroller comparator and the microcontroller power supply accordingly.

EFFECT: improved precision of measurement.
