Description
том усилени . Операционный усилитель 7 управл ет источником питани 6 (-| ).volume gain Operational amplifier 7 controls power supply 6 (- |).
Таким образом, ири воздействии ;.,гстабилизирующих факторов рабоча точка мостовой схемы преобразовател ие мен етс , что существенио повышает точность и надежность измерени .Thus, due to the influence of the stabilizing factors, the operating point of the bridge circuit is transformed, which significantly increases the accuracy and reliability of the measurement.
Дл повышени термостабильности сопротивлени 10 выполн ют в виде терморезисторов .In order to increase the thermal stability, the resistors 10 are in the form of thermistors.
Предмет изобретени Subject invention
Тензометрический преобразователь, содержащий активный четырехплечий тензометрический мост, элементы подстройки параметров моста, операционный усилитель. Индикатор , источник питани , отличающийс тем, что, с целью повышеиии точности и иадеж1юсти , в нем к питающей диагонали моста подключены две параллельные цепи, одна из которых образована последовательно соединенными управл емым и неуправл емым источниками питани , а друга двум последовательно соединенными терморезисторами,Strain gage transducer containing active four-shoulders strain gage bridge, elements for adjusting the parameters of the bridge, operational amplifier. An indicator, a power source, characterized in that, in order to improve accuracy and reliability, there are two parallel circuits connected to the supply diagonal of the bridge, one of which is formed by series-connected controlled and unmanaged power sources, and the other, two series-connected thermistors,
средн точка которых через дополнительный резистор св зана с инвертирующим входом интегрального операционного усилител , выход операционного усилител подключен к схеме регулировани управл емого источника питани .The midpoint of which, via an additional resistor, is connected to the inverting input of the integrated operational amplifier, the output of the operational amplifier is connected to the control circuit of the controlled power source.
