Description
(54) ИНДУКТИВНЫЙ ДАТЧИК ВЛАЖНОСТИ ПОЧВЫ(54) INDUCTIVE SOIL HUMIDITY SENSOR
чивает проводимость этой смолы, что вызывает уменьшение добротности контура.This leads to a decrease in the Q of the circuit.
Таким образом, слой ионитовой смолы, наход щейс между катушкой индуктивности и внутренней стенкой пористого керамического стакана, играет роль вторичной обмотки трансформатора, подключенной к нагрузке, величина которой определ етс проводимостью почвы.Thus, the ionite resin layer located between the inductor and the inner wall of the porous ceramic cup plays the role of the secondary winding of a transformer connected to the load, the magnitude of which is determined by the conductivity of the soil.
Ионнтова смола в значительной степени снижает вли ние растворимых в почвенной влаге солей на величину вносимых активных потерь в катушку индуктивности, вследствие чего иредлагаемый датчик, практически реагирует только на изменение влажности почвы.The iontop resin significantly reduces the effect of salts soluble in soil moisture on the amount of active loss introduced into the inductor, as a result of which the proposed sensor practically only responds to changes in soil moisture.
Описанный датчик позвол ет измер ть влажность почвы в интервале от максимальНО гигроскопической до полной полевой влагоем кости.The sensor described allows measuring soil moisture in the range from maximum hygroscopic to full field moisture of the bone.
