<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">导波雷达物位计是采用微波技术来检测料位的高科技产品,该仪表充分利用了微波具有很好穿透性、对恶劣环境及被测物料适应性强等特点,采用世界上的大规模集成电路,将雷达原理、数字信号处理技术和快速傅里叶变换(FFT)技术。采用连续式乍动测量,能测量液体、固体(块状、粉状)料位,具有测距远、精度高等特点。 *n>*n>*n>*n>

<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">导波雷达物位计发出的高频微波脉冲沿着探测组件(钢缆或钢棒)传播,遇到被测介质,由于介电常数突变,引起反射,一部分脉冲能量被反射回来。发射脉冲与反射脉冲的时间间隔与被测介质的距离成正比。从而计算出探测组件顶部被测介质表面的距离,被测容器总高度是已知数,进一步可得出介质的物位高度。*n>*n>*n>*n>
