摘要
为实时准确监测土壤的水吸力,基于土壤张力计电阻应变原理,研制开发一款结构简单、价格低廉的土壤张力传感器。传感器标定与误差分析结果表明,该传感器的精度与灵敏度较高,能够满足设计要求。
In order to determine the soil matric suction accurately and timely, a soil tension sensor with sample structure and low cost was designed based on soil tensionmeter and according to electric resistance strain theory. The sensor calibration and the error analysis show that the sensor possesses the advantage of high precision and sensitivity, and it is capable of meeting the design requirement.
