Description

Известные, термоэлектрические психрометры, содержащие термометр сопротивлени , термобатарею, «уль-гальванометр и источник тока , имеют низкую точность измерени  и сложную конструкцию.The known thermoelectric psychrometers containing a resistance thermometer, a thermopile, an ul-galvanometer, and a current source have a low measurement accuracy and a complicated structure.

В предлагаемом психрометре нуль-гальванометр и термобатаре  включены тоследовательно в измерительную диагональ моста. Указанное отличие позволило значительно упростить конструкцию психрометра и одновременно повысить точность измерени  относительной влажности .In the proposed psychrometer, a null-galvanometer and a thermopile are subsequently included in the measuring diagonal of the bridge. This difference made it possible to significantly simplify the design of the psychrometer and at the same time improve the accuracy of measuring relative humidity.

На чертеже приведена принципиальна  схема предлагаемого термоэлектрического психрометра, в котором определ емые термоэлектродвижущей силы термобатареи / и компенсаци  вли ни  окружающей температуры на показани  прибора производитс  с помощью неуравновещенного моста, состо щего из сопротивлений 2, 3, 4 н 5, где сопротивление 5 означает термометр сопротивлени .The drawing is a schematic diagram of the proposed thermoelectric psychrometer, in which the determined thermoelectromotive force of the thermopile / and the compensation of the influence of the ambient temperature on the instrument readings is performed using an unbalanced bridge consisting of resistances 2, 3, 4 and 5, where resistance 5 means resistance thermometer .

Термобатаре  1 и нуль-гальванометр 6 соединены последовательно и включены в измерительную диагональ моста. Подобна  схема включени  позвол ет путем изменени  питающего напр жени , подведенно го к клеммам 7 и 8, добитьс  такого положени , что ток, протекающий через нуль-гальванометр 6, будет равен нулю.Thermopile 1 and null-galvanometer 6 are connected in series and included in the measuring diagonal of the bridge. Such a switching circuit allows, by changing the supply voltage applied to terminals 7 and 8, to achieve such a position that the current flowing through the null-galvanometer 6 will be equal to zero.

Так как одна половина термобатареи погружена в ванну 9 с жидкостью и поддерживаетс  влажной, а друга  .половина находитс  в воздухе , то термоэлектродвижуща  сила пропорциональна относительной влажности воздуха. Мерой термоэлектродвижущей силы  вл етс  величина напр жени , подводима  к клеммам 7 и 8 при отсутствии тока в нуль-гальванометре 6.Since one half of the thermopile is immersed in a bath 9 with liquid and kept moist and the other half is in the air, the thermoelectromotive force is proportional to the relative humidity of the air. The measure of thermoelectromotive force is the magnitude of the voltage supplied to terminals 7 and 8 in the absence of current in the null-galvanometer 6.

Предлагаемый психрометр мюжег найти широкое применение в различных лаборатори х, где требуетс  измерение относительной влажности воздуха -с высокой точностью.The proposed psychrometer can be widely used in various laboratories where it is necessary to measure relative humidity of air with high accuracy.
