FIELD: measuring equipment for information controlling of predetermined tillage depth.
SUBSTANCE: apparatus has primary information sensor with two sensitive members connected to different circuits of digital RC-generator of rectangular pulse connected in series with frequency divider and with frequency meter, control unit, reference signal generator, two differential amplifiers, demodulator, comparison circuits and two actuating mechanisms. Control unit is connected to RC-generator, frequency meter and reference signal generator. Actuating mechanism is connected through comparison circuit to demodulator whose inputs are connected through differential amplifier to frequency divider and reference signal generator. Output signal is determined from formula.
EFFECT: increased precision and wider operational capabilities of automatic controlling of predetermined tillage depth.
