Изобретение относитс к контрольноизмерительной технике, а именно к индуктивным преобразовател м давлени .The invention relates to a measurement and control technique, namely, inductive pressure transducers.
В Известных способах измерени параметров преобразователей путем регистрации амплитуды выходного индуктивного преобразовател в зависимости о температуры и выбора оптимального значени данной амплитуды путем регулировани напр жени питани преобразовател компнесаци осуществима только в узком температурном диапазоне l.In the well-known methods of measuring the parameters of the transducers by registering the amplitude of the output inductive transducer depending on the temperature and choosing the optimal value of this amplitude by adjusting the voltage of the transducer supply voltage, the compesna- tion can be performed only in a narrow temperature range l.
Наиболее близким по технической сущности к предлагаемому вл етс способ, по которому регулируют частоту напр жени питани индуктивного преобразовател The closest in technical essence to the present invention is a method by which the frequency of the supply voltage of an inductive converter is regulated
И.AND.
Однако в этом способе ограничена возможность изменени частоты напр жени питани индуктивного преобразовател .However, in this method, the possibility of varying the frequency of the supply voltage of the inductive converter is limited.
Целью изобретени вл етс увеличение точности индуктивных преобразователей давлени за счет уменьшени температурной по1ре1иности.The aim of the invention is to increase the accuracy of inductive pressure transducers by decreasing the temperature range.
Дл этого по предлагаемому способу компенсации температурной погреииюсти индуктивного преобразовател давлени путем регистрации амплитуды выходного сигнала и регулировани частоты напр жени питани , выбирают параметры индуктивного преобразовател по величине его приведенной добротности при минимальной температурной погрешности.To do this, according to the proposed method for compensating the temperature tolerance of an inductive pressure transducer by registering the amplitude of the output signal and adjusting the frequency of the supply voltage, choose the parameters of the inductive transducer according to its reduced quality factor with a minimum temperature error.
На фиг. 1 приведены характеристики температурной погрешности индуктивного преобразовател даншени .FIG. 1 shows the characteristics of the temperature error of the inductive converter dansheni.
Способ реализуетс следующим образом .The method is implemented as follows.
Снимают характеристики температурной погрешности индуктивного преобразовател в зависимости от температуры и частоты питающего напр жени . Определ ют начальную частоту питающего напр жени дл минимальной температурной погрешности- ( опт 2,2 кГц). Определ ют параметры индуктивного преобразовател (индуктивность, сопротивление и приведенную добротность).The characteristics of the temperature error of the inductive converter are removed depending on the temperature and frequency of the supply voltage. The initial frequency of the supply voltage is determined for a minimum temperature error (opt 2.2 kHz). The parameters of the inductive converter (inductance, resistance and reduced Q) are determined.
