用 途：石油管道防腐层检测、燃气管道防腐层检测
燃气石油管道外反腐层检测仪RD400PCM+的系统特点 由便携式发射机和手提式接收机组成。发射机馈送一种接近直流的信号电流给管道,接收机对沿管道传送的这种特殊信号电流进行探测，并显示出信号电流的强度和方向,即使在管道与其它金属结构接触，或有干扰，或管道拥挤的情况下，都能准确、容易地对管道进行定位，并绘制管线图能给出管道上电流的分布和电流的方向，该电流实际上就是管道上的CP电流*的评估管道的防腐层状况，低虚假指示，减少不必要的开挖提供数据记录，并通过蓝牙和PDA或PC连接现场审视图形配上A字架，*定位防腐层破损点减少了工作和维修费用，提高测量速度,PCM系统的专用大功率发射机能使信号的检测距离长达３0公里。
Product info
Combined with its new high performance transmitter the PCM+ accurately and easily locates and maps the pipeline for up to 19 miles, providing simultaneous measurement of PCM Current and Voltage Gradient, even in areas where there is contact with other metallic structures, interference, or congestion. This eliminates the need for the pipeline technician to perform direct connection 'current spans' and manual calculations to determine CP currents along the pipeline reducing false indications and minimizing unnecessary excavations. Any current leakage fault in the pipeline coating can be further narrowed down to within 3 feet by use of the A frame.
