简要描述:

1.原理

江苏脉冲雷达料位计天线发射极窄的微波脉冲,这个脉冲以光速在空间传播,遇到被测介质表面,其部分能量被反射回来,被同一天线接收。发射脉冲与接收脉冲的时间间隔与天线到被测介质表面的距离成正比,从而计算出天线到被测介质表面的距离。

2.优点

雷达物位计采用了高达26GHz的发射频率,因而具有:
  -波束角小(最小5度),能量集中,具有更强抗干扰能力,大大提高了测量精度和可靠性;
  -天线尺寸小,便于安装和加装防尘罩等天线防护装置;
  -测量盲区更小,对于小罐测量也会取得良好的效果;
  -波长更短,对小颗粒物质的料位测量更适合。

欧洲杯比分2.GUANYUPAOMODUICELIANGDEYINGXIANG:

干泡沫和湿泡沫能将雷达波反射回来,对测量无影响;中性泡沫则会吸收和扩散雷达波,因而严重影响回波的反射甚至没有回波。当介质表面为稠而厚的泡沫时,测量误差较大或无法测量,在这种工况下,江苏脉冲雷达料位计不具有优势,这是其应用的局限性。
