Изобретение относитс к электроизмерительной технике, а именно к измерению перемещений при помснци дифференциальных емкостных датчиков.The invention relates to electrical measuring equipment, namely to measuring displacements with the replacement of differential capacitive sensors.
По основному авт.св. f 861925 известен емкостной трансформаторный мост дл измерени перемещений, содержащий трансформатор напр жени коммутатор, компаратЬр токов с регулируемой и двум дифференциальными ,Q обмотками, блок уравновешив.ани , дифференциальный емкостной преобразователь перемещени х переменной активной площадью, с потенциальным электродом , подключенным к вторичной об- 5 мотке трансформатора напр жений, токовым электродом, разделенным на механически жестко скрепленные между собой секции, и подвижным экранирующим электродом с окнами, располо- 20 женным между токовым и потенциальным электродами, количество секций токового электрода выбрано равным или больше п ти, подвижный экранирующий электрод выполнен с количеством окон, равным или больше двух, компаратор токов выполнен с обмоткой смещени , включенной последовательно с регулируемой обмоткой, а коммутатор включен между токовым электродом и компаратором токов tOНедостатками известного устройства вл ютс относительно низка точность измерени , ограниченна точностью изготовлени секций токового электрода, а также узкий диапазон измерени .According to the main auth. The f 861925 is known for a capacitive transformer bridge for measuring displacements, which contains a voltage transformer switch, a comparative current with adjustable and two differential, Q windings, a balancing unit, a differential capacitive transducer of displacements with a variable active area, with a potential electrode 5 coil of voltage transformer, current electrode divided into sections mechanically rigidly fastened among themselves, and movable shielding electrode with windows, located between the current and potential electrodes, the number of sections of the current electrode is equal to or more than five, the movable screening electrode is made with the number of windows equal to or more than two, the current comparator is made with an offset winding connected in series with the adjustable winding, and the switch is on between the current electrode and the current comparator tO The disadvantages of the known device are relatively low measurement accuracy, limited by the accuracy of manufacturing the current electrode sections, and also cue range measurement.
Цель изобретени - расширение диапазона и увеличение точности измерений .The purpose of the invention is to expand the range and increase the accuracy of measurements.
