Description
Напр жени с амплитудой U. Линейно-измен ющеес напр жение с выхода интегратора 2 подаетс на неинвертирующий вход операционного усилител 3.Voltages with an amplitude U. The linearly varying voltage from the output of the integrator 2 is fed to the non-inverting input of the operational amplifier 3.
Напр жение с выхода датчика 5 подаетс на один вход устройства 7, а напр жение UQ через делитель 6 напр жени с коэффициентом передачи Va - На другой его вход.The voltage from the output of the sensor 5 is applied to one input of the device 7, and the voltage UQ through the voltage divider 6 with the transfer coefficient Va to its other input.
Этот сигнал подаетс на один вход элемента 1 сравнени , на другой вход которого подаетс его выходное напр жение.This signal is applied to one input of the reference element 1, to the other input of which its output voltage is applied.
В момент равенства напр жений на входах элемента 1 сравнени выходное напр жение последнего скачкообразно измен ет знак на противоположный, описанный процесс повтор етс .At the time when the voltages are equal at the inputs of the comparison element 1, the output voltage of the latter abruptly changes the sign to the opposite, the described process repeats.
Преобразователь работает в автоколебательном режиме. Период автоколебаний определ етс следующим образомThe converter works in the auto-oscillatory mode. The self-oscillation period is defined as follows.
.тт) . m)
где Ro - сопротивление опорного резистора 4; Аг - разность активных сопротивленийwhere Ro is the resistance of the reference resistor 4; Ar - the difference of active resistances
обмоток датчика 5; AL - разбаланс датчика 5; Тн - посто нна времени интегратора 2. Сравнительный анализ погрешностей данного и известного преобразователей показывает , что погрешность преобразовани , обусловленна вли нием активных сопротивлений обмоток датчика 5, у данного преобразовател существенно ниже. Погрещность, обусловленна неидентичностью опорных резисторов в известном преобразователе, в предлагаемомwindings of sensor 5; AL - unbalance sensor 5; T is the time constant of the integrator 2. A comparative analysis of the errors of this and known transducers shows that the conversion error due to the influence of the active resistance of the windings of sensor 5 is much lower for this converter. Fault, due to the non-identity of the reference resistors in the known converter, in the proposed
преооразователе отсутствует, что позвол ет использовать его дл точных измерений и расширить номенклатуру используемых датчиков .There is no transducer, which allows it to be used for accurate measurements and to expand the range of sensors used.
