摘要(Abstract):

【目的】确定水肥一体机EC传感器最佳安装角度。【方法】通过试验测定不同安装角度条件下,肥液的电导率值。【结果】从偏差系数可以看出,90°条件下(EC传感器处于水平位置),EC传感器所测得的EC值波动范围最小,其EC监测通道监测效果最好。且90°、135°、180°条件下,EC监测通道的监测效果要明显优于0°和45°条件。【结论】水肥一体机的EC传感器最佳安装角度为90°。同时,为避免溶质粘附在EC传感器的电极上面影响测量精度,应选用90(°水平方向)安装EC传感器,而不采用135°和180°条件安装。
【Objective】Determine the optimal installation Angle of EC sensor【.Method】The conductivity of fertilizer solution was tested under different installation angles【.Result】Based on the deviation factor, 90 °(EC sensors in a horizontal position), under the condition of EC sensor measured by the EC minimum value range, its EC channel monitoring effect was best. And 90 °, 135 °, 180 °, under the condition of EC channel monitoring effect was significantly better than that of 0 ° and 45 ° conditions【.Conclusion】The optimum installation angle of EC sensor of the water and fertilizer integrated machine was 90°.
