电传感器设备用作监视喷头滴灌砂质土湿润情况的变化。本文对两种电传感器（探头传感器和桶式传感器）的设计作评价。用手把“Equqailie”细砂装入一个直径为1，2m，深度为35cm的容器中，在填料过程中，安放电传感器于纵断面上。点水源滴头以1．5～1．91／h的速度供给用水。以9
Electric sensor device is used to monitor the change of wet conditions of drip irrigation sandy soil. This article evaluates the design of two types of electrical sensors (probe and barrel sensors). Put the “Equqailie” fine sand in a container with a diameter of 1, 2 m and a depth of 35 cm by hand. During the filling process, place the electrical sensor on the longitudinal section. Point water drip to 1.5 ~ 1.91 / h speed of water supply. With 9
