Description
Известны приборы дл определени влажности почвы по электропроводности ее, в которых применены погружаемые в исследуемую почву электроды.Instruments are known for determining soil moisture by its electrical conductivity, in which electrodes are immersed in the soil under study.
В предлагаемом приборе, с целью измеренп одновременно с электропроводностью почвы и ее температуры, к каждому из электродов -присоединены термопары .In the proposed device, in order to measure simultaneously with the electrical conductivity of the soil and its temperature, thermocouples are attached to each of the electrodes.
На чертеже фиг. 1 изображает верхнюю часть прибора; фиг. 2-нижнюю часть его.In FIG. 1 shows the upper part of the device; FIG. 2 is the bottom of it.
Предлагаемый прибор (фиг. 1 и 2) состоит из электродов 3, вставл емых в почву, которые и снабжены дл измерени температуры почвы термопарами 5, 6 (медь-константан) Вторые концы термопар через трубку вывод тс наружу и привинчиваютс к штепсельным гнездам. Электроды 3 дл посто нных установок выполн ютс из неокисл ющегос металла, а дл пореиосных- из красной меди.The proposed device (Figs. 1 and 2) consists of electrodes 3 inserted into the soil, which are equipped with thermocouples 5, 6 (copper-constantan) for measuring the temperature of the soil. The second ends of the thermocouples are brought out of the tube through the tube and screwed onto the plug sockets. Electrodes 3 for permanent installations are made of a non-oxidizing metal, and for copper, of red copper.
Весь прибор включаетс в мост Кольрауша в качестве искомого сопротивлени . Коробка 2 загружаетс тающим льдом дл отсчета на гальван метре температуры от 0°. Верхн часть 4 прибора (фиг. 1) вставл етс в нижнюю 1, как штепсель.The entire device is included in the bridge of Kohlrausz as the sought resistance. Box 2 is loaded with melting ice for reading on a galvan temperature meter from 0 °. The upper part 4 of the device (Fig. 1) is inserted into the lower 1, as a plug.
Таким образом, одновременно с электропроводностью определ етс и температу ра почвы. Влажность же почвы вл етс иараболической функцией электропроводности .Thus, simultaneously with the electrical conductivity, the temperature of the soil is determined. Soil moisture is the aarabolic function of electrical conductivity.
Предмет изобретени .The subject matter of the invention.
Прибор дл определени влажности почвы по электропроводности ее с применением погружаемых в почву электродов , включенных в цепь источника тока, отличающийс тем, что к каждому из электродов 3 присоединена термопара, с целью измерени одновременно с электропроводностью п температуры почвы.A device for determining soil moisture by its electrical conductivity using electrodes immersed in the soil and connected to a current source circuit, characterized in that a thermocouple is attached to each of the electrodes 3 to measure simultaneously with the electrical conductivity n of the soil temperature.
