  • Measurement Of Resistance Or Impedance (AREA)

Description

Дл  измерени  больших сопротивлений (пор дка ом) известно применение мостов, одно из плеч которых выполнено в виде плавно регулируемого сопротивлени , а другое - дл  обеспечени  достаточной чувствительности - в виде непроволочпого сопротивлени  большой величины (пор дка 10 -lOi ом.For measuring large resistances (on the order of ohms), it is known to use bridges, one of the arms of which is made in the form of a continuously adjustable resistance, and the other to provide sufficient sensitivity in the form of a large non-wire resistance (on the order of 10-1Oi.

Так как непроволочные сопротивленн  нестабильны во времени и их точность не может быть больше нескольких процентов, то в таких мостах прибегают к контролю величины указанного сопротивлени , дл  чего к зажимам моста перед подключением измер емого сопротивлени  подключают точное образцовое еолротивление.Since non-wired resistances are unstable in time and their accuracy cannot be more than a few percent, in such bridges they resort to monitoring the value of the specified resistance, for which purpose the exact reference resistance is connected to the terminals of the bridge before connecting the measured resistance.

При этом измерение св зано с необходимостью дополнительных вычислений.In this case, the measurement is associated with the need for additional calculations.

С целью устранени  этого недостатка и обеспечени  тем самым возможности ускорени  и упрощени  процесса измерени , предлагаетс  дл  контрол непроволочного сопротивлени  применить два дополнительных плеча отношени , подключаемые к мосту вместо плеч с измер емым и -соответственно эталонным сопротивлени ми.In order to eliminate this disadvantage and thereby ensure the possibility of accelerating and simplifying the measurement process, it is proposed to use two additional ratio arms, connected to the bridge instead of the arms with the measured and, respectively, reference resistances, to control the nonwire resistance.

На чертеже показана схема предлагаемого моста дл  измерени  больших сопротивлений.The drawing shows a diagram of the proposed bridge for measuring high resistances.

В этом мосте одно плечо выполнено в виде магазина сопротивлений Г, другое плечо состоит из посто нного сопротивлени  и последовательно с ним включенного реостата Гг и третье плечо представл ет собой непроволочное сопротивление Гз.In this bridge, one shoulder is made in the form of a resistance box G, the other shoulder consists of constant resistance and, consistently with it, an included rheostat Gg and the third shoulder is a nonwire resistance Gz.

В схему моста введены переключатель Я и два дополнительных нлеча отложени  г и одно из которых г подключаетс  вместо п еча с измер емым сопротивлением г j. , а другое - вместо плеча с эталонным сопротивлением Г. Отношени  величин сопротивлений- - Ш.A switch Я and two additional nlets of deposition r are entered into the bridge circuit, and one of which r is connected instead of a seal with a measured resistance rj. , and another - instead of a shoulder with a reference resistance G. Relationship of resistance values - - Sh.
