| 摘 要： | 本文利用水的介电常数远大于一般介质介电常数的特点，发展了一种测量松散颗粒物料局部湿含量的电容探针。由于采用误差补偿电路和针型传感器探头，并在结构上采用了减小损耗的措施，提高了探针的灵敏度、稳定性和空间分辨率，可以用于松散颗粒物料局部湿含量的测量。

| Abstract: | A mini-capacitance probe for measuring the local moisture content in the granular porous material is developed in this paper. By using error compensation circuit and the methods to decrease theloss tangent, the high sensitivity, stability and spatial resolving power for the mini-capacitance probe are reached. The experimental results show that the measurement of the local moisture content in the granular porous material by this mini-probe is successful and the probe can be used in engineering practice. |
