  • Measurement Of Resistance Or Impedance (AREA)

Description

Величины pi и 01 определ ютс  экспериментальным путем дл  данных условий эксплуатации .The values of pi and 01 are determined experimentally for these operating conditions.

Зна  оь наход т новое начальное значение сопротивлени  термометра о из условий равенства наклона его статической характеристики с градуировочной характеристикой прибораKnow the new initial value of the resistance of the thermometer and from the conditions of equality of the slope of its static characteristic with the calibration characteristic of the device

Р - о tga ° ° IglT P - about tga ° ° IglT

где Рг - угол наклона градуировочной характеристики стандартного прибора.where Pr is the angle of inclination of the calibration characteristic of a standard instrument.

Статическа  характеристика непогруженного термометра с начальным сопротивлением 0 соответствует характеристике 3. Чтобы совместить характеристики 2 и 3 в смежное плечо моста включают переменный термонезависимый резистор и, измен   его величину, добиваютс  совпадени  характеристик 2 и 3.The static characteristic of a non-immersed thermometer with an initial resistance of 0 corresponds to characteristic 3. In order to combine characteristics 2 and 3, a variable temperature-independent resistor is inserted into the adjacent bridge arm and, by changing its value, characteristics 2 and 3 are achieved.
