Abstract
Изобретение относитс к измерительной технике и может быть использовано дл измерени давлени в почвах. Цель изобретени - упрощение конструкции и повышение надежности. С одного торца корпуса 2 установлена эластична пробка 4, а с другого - пористое тело (зонд) 1. Корпус 2 частич- но заполнен жидкостью и газовым пузырьком 3. На эластичной пробке 4 посредством стоек 5 установлен контейнер 6 с герметиком. При измерении давлени иглой 9 манометра с капилл ром 7 прокалывают пробку и размещают конец иглы 2 в газовом пузырьке 3 над контейнером 6 с герметиком . После чего манометр продвигают так, чтобы конец иглы 9 оказалс в контейнере 6 с герметиком, Герметик. оставшийс на конце иглы 9, отдел ет капилл р манометра от атмосферы и фиксирует показани величины давлени в газовом пузырьке. Затем величину давлени вычисл ют по известным формулам. 5 ил. СП СThe invention relates to a measurement technique and can be used to measure pressure in soils. The purpose of the invention is to simplify the design and increase reliability. At one end of the housing 2, an elastic plug 4 is installed, and on the other, a porous body (probe) 1. The housing 2 is partially filled with liquid and a gas bubble 3. On the elastic plug 4, a container 6 with a sealant is mounted by means of the racks 5. When measuring the pressure with a needle 9 of a manometer with a capillary 7, a stopper is pierced and the end of the needle 2 is placed in the gas bubble 3 above the container 6 with a sealant. After that, the pressure gauge is advanced so that the end of the needle 9 is in the container 6 with a sealant, a sealer. the remainder at the end of the needle 9 separates the capillary of the manometer from the atmosphere and records the readings of the magnitude of the pressure in the gas bubble. The pressure is then calculated by the known formulas. 5 il. THX
