На чертеже приведена структурная электрическая схема устройства для проверки самобалансирующихся Термисторных мостов, реализующего предлагаемый способ. 10The drawing shows a structural electrical circuit of the device for testing self-balancing Thermistor bridges that implements the proposed method. ten
Устройство для проверки самобалансирующихся термисторных мостов содержит эталонный резистор 1, источник 2 постоянного напряжения, включенные в рабочее плечо 3.проверяв- 15 мого самобалансирующегося термисторного моста 4.The device for testing self-balancing thermistor bridges contains a reference resistor 1, a constant voltage source 2 included in the working arm 3. of the checked 15 self-balancing thermistor bridge 4.
Способ проверки самобалансирующихся термисторных мостов реализуется следующим образом.The method of testing self-balancing thermistor bridges is implemented as follows.
И) 2AND 2
В рабочее плечо проверяемого самобалансирующе гося термисторного моста вместо рабочего термистора включают последовательно соединенные эталонный резистор 1 и источник 2 постоянного напряжения. Включают ·, проверяемый самобалансирующийся тер-, мисторный мост в рабочий режим и пос ле его балансировки измеряют с помощью вольтметров 5 и 6 напряжения на эталонном резисторе 1 и рабочем плече Зи< и ϋ2 .Instead of the working thermistor, a series-connected reference resistor 1 and a constant voltage source 2 are connected to the working arm of the tested thermistor bridge instead of the working thermistor. Turn on the tested, self-balancing thermal, mystor bridge into the operating mode and after its balancing is measured using voltmeters 5 and 6 of the voltage across the reference resistor 1 and the operating arm Zi <and 2 .
Действительное значение рабочего сопротивления определяют по формуле *The actual value of the working resistance is determined by the formula *
где К-э - сопротивление эталонного ре зистора 1.where K-e is the resistance of the reference resistor 1.
