Description
ТЭДС от температуры. Поэтому в каждый момеда дардамени на выходе демодул тора Ь паЙб етсч напр жение, .пропорцио ,,-тёмпературе, измер емой терMotiaport . 1; или 2, в зависимостк от по .)gHflt.коммутатора 3. В зависимости -Ьт по бжейи модул тора 3 и коммутатора Ь, работающих синхронно, на одной из выходов коммутатора 8 по витс импульсное напр жение (с чacтoтoй работы коммутатора 8). величина которого пропорциональна, абсолютному значению температуры, измер емой термопарой iJ.TEDS on temperature. Therefore, in each moment of dardameni, at the output of the demodulator L of the PCE, the voltage, Proportion, is the temperature measured by the term Motiaport. one; or 2, depending on the.) switchboard 3. switchboard 3. Depending on the modulator 3 and switch b, working synchronously, one of the outputs of switch 8 gives the pulse voltage (from the switch 8 operation frequency). the value of which is proportional to the absolute value of the temperature measured by the thermocouple iJ.
С помощью разделительных конденсаторов У и 10 выдел етс переменна составл юща каждого из этих напр жений , которые демодулируютс демодул торами 12 и 13 и измер ютс двум приборами 15 и 16.Using coupling capacitors Y and 10, the variable component of each of these voltages is extracted, which are demodulated by demodulators 12 and 13 and measured by two instruments 15 and 16.
Если напр жени на термопарах 1 и 2 отличаютс , то на выходе демодул тора 6 по витс переменна составл юща напр жени , величина которой пропорциональна разности измер емых температур , а фаза зависит от знака этой разности. Эта переменна составл юща выдел етс с помощью соответствующего конденсатора 11, демодулируе/с и измер етс третьим прибором 17, предназначенным дл измерени разности температур Ai а tj -t If the voltages on thermocouples 1 and 2 are different, then at the output of demodulator 6, the voltage component is variable, the value of which is proportional to the difference in measured temperatures, and the phase depends on the sign of this difference. This variable component is extracted using an appropriate capacitor 11, demodulating / s, and is measured by a third device 17, designed to measure the temperature difference Ai and tj -t
Таким образом, предложенное устройство позвол ет одновременно измер ть разность температур; «tj-t и абсолютные значени обоих темперас Typ(t J М tj,) при наличии линейной зависимости ТЭДС от температуры.Thus, the proposed device allows simultaneous measurement of the temperature difference; "Tj-t and the absolute values of both temperature types Typ (t J M tj,) in the presence of a linear temperature dependence of the TEC.
Предлагаемое устройство обеспечивает измерение абсолютных значений )0 температуры одновременно с измерением разности температур, отпадает необходимость в использовании дополнительных устройств.дл измерени абсолютны значений температур.The proposed device provides a measurement of the absolute values of the temperature simultaneously with the measurement of the temperature difference, eliminating the need for the use of additional devices for measuring the absolute values of the temperatures.
