Description
В известных установках дл скоростного определени теплофнзнческих констант по методам регул рного теплового режнма примен ютс высокс чувствнтельные зеркальнь е гал1 ванометры, показанн которых записываютс экспериментаторами:In the known installations for the high-speed determination of heat-transfer constants by the methods of the regular thermal regime, high-sensitivity mirroring of gal1 vanometers are used, the recordings of which are recorded by experimenters:
Особенностью описываемой установк вл етс применение, зеркального гальванометра, самопишущего милливольтметра, подсоединепного к выходу однокаскадного дифференциального магнитного усилител , к входу которого подключен датчик температурпой разности.A special feature of the installation described is the use of a mirror galvanometer, a recording millivoltmeter connected to the output of a single-stage differential magnetic amplifier, to the input of which the differential temperature sensor is connected.
Такое применение самопищуи1его мпллпвольтметра позволи.ю автоматизировать процесс и повысить точность определени теплофпзических констант.Such an application of a self-powered mlnpvoltmetra allows you to automate the process and improve the accuracy of the determination of thermal constants.
На чертеже показана схема установки. Установка выполнена в впде калориметра / с мешалкой 2 п термометром 3. В термостатированной жидкой среде 4 располагаетс испытываемый образец 5 и медно-константанова термопара 6, выполн юща ро,1ь датчика-пзмернтел температурной разности. Возбуждаема термопарой электродвижуща снла фиксируетс самопищущим милливольтметром 7, подсоединенным к термопаре 6 посредством однокаскадного дифференцнального магнитного усилител 8, нолучающего питание от сети через стабилизатор напр жени 5.The drawing shows the installation diagram. The installation was performed in a calorimeter / mixer with a 2 p thermometer 3. In a thermostated liquid medium 4, a test sample 5 and a copper-constantan thermocouple 6 are located, which performs a thermal sensor temperature differential sensor. An electromotive actuated by a thermocouple is fixed by a self-powered millivoltmeter 7 connected to the thermocouple 6 by means of a single-stage differential magnetic amplifier 8, which receives power from the network through a voltage stabilizer 5.
