Изобретение относитс к области измерительной техники и может быть использовано дл непрерывного опреде лени влажности почв, осадочных горных пород, дисперсных материалов и т.п., в особенности грунтов в услови х природного залегани дл строительных целей.The invention relates to the field of measurement technology and can be used for the continuous determination of soil moisture, sedimentary rocks, dispersed materials, etc., especially soils under natural conditions for building purposes.
Известен индуктивный датчик влажности почвы, включающий керамический стакан с ионитовой смолой, чувствительный элемент, пружину дл уплотнени смолы, в котором дл повышени точности и чувствительности измерений чувствительный элемент выполнен в виде катушки индуктивности, поме .ценной в ионитовую смолу, расположженную между катушкой, индуктивности и внутренней стенкой керамического стакана ||l .An inductive soil moisture sensor is known, including a ceramic cup with an ion exchange resin, a sensing element, a spring for compressing the resin, in which the sensitivity element is designed as an inductance coil located in the ion exchange resin between the coil, inductance and the inner wall of the ceramic cup || l.
Недостатком устройства вл етс невозможность измерени влажности в диапазоне положительных и отрицательных температур, обусловленна особыми свойствами использованного чув- , ствительного элемента, а также активное воздействие на чувствительный элемент и окружающий анализируемый грунт электромагнитного пол , что вызывает погрешности из-за перераспределени влаги за счет активного искусственного воздействи . Кроме того, при отрицательных темпера10 турах лед разрушает керамический стакан, что снижает долговечность устройства.The drawback of the device is the impossibility of measuring the humidity in the range of positive and negative temperatures, due to the special properties of the sensing element used, as well as the active influence on the sensitive element and the electromagnetic field surrounding the analyzed soil, which causes errors due to the redistribution of moisture impact. In addition, at negative temperatures, ice destroys a ceramic cup, which reduces the durability of the device.
