Description

В ОСНОВНОМ авт. св. № 103505 описано устройство дл  измерени  разностей температуры и влал ностн в приземном слое воздуха психрометрическим способом с применением в качестве «сухих и «смоченных термометров термосопротйвлений. Особенностью этого устройства  вл етс  то, что полупроводниковые термосопротивлени , служащие в качестве сухих термометров, включены в плечи одного дифференциального моста, а полупроводниковые термосопротивлени , служащие в качестве «смоченных термометров, включены в плечи другого дифференциального моста, что позвол ет производить непосредственный отсчет значений малых разностей температуры и абсолютной влажности воздуха .BASIC Auth. St. No. 103505 describes a device for measuring the difference in temperature and temperature in the surface air layer by a psychrometric method using thermoprotections as dry and wet thermometers. A feature of this device is that semiconductor thermistors, serving as dry thermometers, are included on the shoulders of one differential bridge, and semiconductor thermistors, serving as wetted thermometers, are included on the shoulders of another differential bridge, which allows a direct reading of small values differences in temperature and absolute humidity.

Предлагаемое устройство  вл етс  развитием указанного основного изобретени  и имеет целью обеспечить непосредственный отсчет значений плотности вод ного пара. Это достигаетс  подсоединением параллельно измерительному прибору цепочки из полупроводникового термосопротивлени  и посто нного сопротивлени .The proposed device is a development of this basic invention and is intended to provide a direct reading of the values of the density of water vapor. This is achieved by connecting in parallel to the measuring instrument a chain of semiconductor thermal resistance and constant resistance.

На чертеже изображена принципиальна  электрическа  схема описываемого устройстваУстройство состоит из двух дифференциальных мостов / и .2, питаемых от источников 3, 4 посто нного тока. В плечи моста / включены посто нные сопротивлени  5, 6, 7 -л полупроводниковое термосопротивление 8, служащее в качестве «сухого термометра. В плечи моста 2 включены посто нные сопротивлени  9, 10, 11 и полупроводниковое термосопротивление 12, служащее в качестве «смоченного термометра.The drawing shows a circuit diagram of the device described. The device consists of two differential bridges / and .2, fed from sources 3, 4 of direct current. The shoulders of the bridge / include constant resistances of 5, 6, 7 -l semiconductor thermal resistance 8, which serves as a dry thermometer. The arms of bridge 2 include constant resistances 9, 10, 11, and semiconductor thermal resistance 12, which serves as a wetted thermometer.

Параллельно измерительным лтиагонал м мостов /, 2 подключен электроизмерительный прибор 13. Дл  того, чтобы показани  электроизмерительного прибора 13 были пропорциональны плотности вод ного пара, параллельно прибору подсоедин ют цепочку, состо пхую из полуIn parallel with the measuring bridge m /, 2, an electrical measuring device 13 is connected. In order for the reading of the electrical measuring device 13 to be proportional to the density of water vapor, a chain is connected in parallel to the device;
