| 一、MTU800系列脉冲型雷达物位计 测量原理
发射能量很低的微波脉冲通过天线系统发射并接收。运行时间可以通过电子部件被转换物位信号。一种特殊的时间延伸方法可以确保极短时间内稳定和精确的测量。
即使工况比较复杂的情况下，存在虚假回波，用的微处理技术和调试软件也可以准确的分析出物位的回波。
输 入
天线接收反射的微波脉冲并将其传输给电子线路，微处理器对此信号进行处理，识别出微脉冲在物料表面所产生的回波。正确的回波信号识别由智能软件完成，精度可达到毫米级。距离物料表面的距离D与脉冲的时间行程T成正比：
D=CXT/2
其中C为光速
因空罐的距离E已知，则物位L为
L=E-D
输 出
通过输入空罐高度E（=零点），满罐高度F（=满量程）及一些应用参数来设定，应用参数将自动使仪表适应测量环境。对应于4～20mA输出。
应用介质
脉冲系列雷达物位计适用于对液体、浆料及颗粒料的物位进行非接触式连续测量，适用于温度、压力变化大，有惰性及挥发性气体存在的场合。
采用微波脉冲的测量方法，并可在工业频率波段范围内正常工作。波束能量较低，可安装于各种金属、非金属容器或管道内，对人体及环境均无伤害。
