Description
(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ РАЗНОСТИ ТЕМПЕРАТУР(54) DEVICE FOR DIMENSION OF DIFFERENCE TEMPERATURES
;; ;;
изобретение относитс к измерительной технике. The invention relates to measurement technology.
: Известны устройства дл измерени разности температур с помощью мостовой схе . мы, в каждое из плеч которой включены: Known devices for measuring temperature differences using a bridge circuit. we, in each of whose shoulders are included
термометры сопротивлени . Однако в такой схеме выходное напр жение в измерите ьной диагонали моста зависит не только от разности, но и от суммы абсолютных значе НИИ температур.resistance thermometers. However, in such a scheme, the output voltage in the measured diagonal of the bridge depends not only on the difference, but also on the sum of absolute values of the scientific research institute of temperatures.
Известны также устройства дл измерени температуры, содержащие термочувствительный мост и термометр сопротивлени , помешенный в измер емую среду. Однако в этой схеме на результат измерени вли ют колебани напр жени источника посто нного тока.Temperature measuring devices are also known, comprising a temperature-sensitive bridge and a resistance thermometer placed in the medium to be measured. However, in this circuit, fluctuations in the DC voltage source influence the measurement result.
) . изобретени - повышение точности и создание возможности автоматического измерени разности температур, .). invention - improving accuracy and creating the possibility of automatically measuring the temperature difference,.
Дл эторо в предлагаемом устройстве термочувствительный мост включен во втсн. ричную обмотку трансформатора тока, аFor Etoro, in the proposed device, a heat sensitive bridge is included in VTSN. the rich winding of the current transformer, and
последовательно с первичной обмоткой включень реохорд, зашунтированный посто ннымнconsistently with the primary winding, a re-chord, permanently shunted
ТаПеременным резисторами дополнительный термометр сопротивлени и добавочный резистор , зашунтированные резистором, а i переменный резиС5тор включен последовательно с диагональю термочувствительнот о моста и реохордом в схему уравновешивани An alternating resistor is an additional resistance thermometer and an additional resistor, which is shunted by a resistor, and i is a variable resistor connected in series with the diagonal of the thermal sensitivity of the bridge and the resistor in the balance circuit
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Разность температур H3NiepHeTCH термометрами 1 и 2 сопротивлени51, включенными в смежные плечи термочувствительного моета , в два других плеча которого включены резисторы 3 и 4. Термочувствительный мост соединен со вторичной обмоткой трансформатора 5 тока. Последовате;пьно с первичной обмоткой включен узел реохорда, состо щий из реохорда 6 измерительного лрибора, защунтированного резисторами 7, ,8 и 9, причем резисторы 7 и 9 посто нные , а резистор 8 - переменный.The temperature difference between the H3NiepHeTCH thermometers 1 and 2 of the resistance51 included in the adjacent arms of the heat-sensitive washer, the other two arms of which include resistors 3 and 4. The heat-sensitive bridge is connected to the secondary winding of the current transformer 5. Consistently with the primary winding, a reichord node is included, consisting of a reichord 6 measuring rim, ground by resistors 7,, 8 and 9, the resistors 7 and 9 being constant, and the resistor 8 is variable.
Последовательно с реохордом 6 включены дополнительный термометр сопротивлени 10 и добавочный резистор 11, при .4eNt реохорд в, термометр сопротивлени An additional resistance thermometer 10 and an additional resistor 11 are connected in series with the reocord 6, at 4 ° N retoch in, the resistance thermometer
