Abstract
Изобретение относитс к измерительной технике и может быть использовано дл автоматизации измерений и контрол перемещений объектов, св занных с подвижным электродом потенциометрического датчика. С целью повышени точности за счет снижени вли ни температурной погрешности в преобразователь, содержащий интегратор 1, потенциометрический датчик 2, дифференциальный усилитель 3 и компаратор 4, введен делитель 5,-а датчик 2 включен вцепь обратной св зи интегратора 1 так, что датчик 2 и интегрирующий конденсатор образуют последовательную цепь. Период следовани импульсов на выходе преобразовател зависит только от разбаланса датчика 2, поэтому исключено вли ние полного сопротивлени датчика 2 и его температурных изменений. 2 ил.The invention relates to a measurement technique and can be used to automate measurements and control the movements of objects associated with a moving electrode of a potentiometric sensor. In order to increase accuracy by reducing the effect of temperature error in the converter containing integrator 1, potentiometric sensor 2, differential amplifier 3 and comparator 4, divider 5 is inserted, and sensor 2 includes feedback circuit of integrator 1 so that sensor 2 and integrating capacitor form a series circuit. The pulse period at the output of the converter depends only on the unbalance of sensor 2, therefore, the influence of the impedance of sensor 2 and its temperature changes is excluded. 2 Il.
