Description
(5) ЕМКОСТНОЙ ТРАНСФОРМАТОРНЫЙ МОСТ ДЛЯ ИЗМЕРЕНИЯ ПЕРЕМЕЩЕНИЙ(5) CAPACITY TRANSFORMER BRIDGE FOR MEASUREMENT OF MOVEMENTS
1one
Изобретение относитс к измерительной технике, а именно к измерению перемещений с помощью дифференциальных емкостных преобразователей.The invention relates to a measurement technique, in particular to measuring displacements using differential capacitive transducers.
Известны устройства дл измерени перемещений при помощи емкостных дифференциальных преобразователейII3.Devices are known for measuring displacements using capacitive differential transducers II3.
Недостаток устройств закл эчаетс в большой погрешности измерени , обусловленной неидеальностью характерис-jQ тик преобразовател .The lack of devices is a result of a large measurement error due to the imperfection of the characteristic jQ transducer.
Наиболее близким по технической сущности к предлагаемому вл етс емкостной трансформаторный мост дл измерени перемещений, содержащий ,5 трансформатор напр жени , коммутатор, компаратрр токов, дифференциальный емкостной преобразователь перемещений с переменной активной площадью с токовым электродом, разделенным на 20 механически жестко св занные между со бой секции, подключенные через коммутатор к компаратору токов, и блок уравновешивани 23.The closest in technical essence to the present invention is a capacitive transformer bridge for measuring displacements, comprising, 5 voltage transformer, switch, current comparator, differential capacitive displacement transducer with variable active area with current electrode divided by 20 mechanically rigidly connected between sections connected via a switch to a current comparator and balance unit 23.
Недостаток известного устройства заключаетс в большой динамической погрешности измерени .A disadvantage of the known device is the large dynamic measurement error.
Цель изобретени - уменьшение динамической погрешности.The purpose of the invention is to reduce the dynamic error.
