介绍了一种脉冲数字式射线传感器，由盖革计数管、高压电源、专用模块及可编程控制器软件组成。电路采用了模块设计，通过使用专用模块，简化了硬件电路，基本不需要调试。传感器的响应时间、灵敏度能通过可编程控制器分别进行调节。采用脉冲数字式射线传感器的射线管道爬行器具有灵敏度高、稳定性高、误动作少的特点。

A pulse digital X-ray sensor, which is composed of Geiger counter, high voltage power, specified model and PLC, was introduced. The modular design of circuit made the hardware simple and without the need of debugging. The response time and sensitivity of sensor can be regulated by PLC. The pipe crawler with the sensor has the characteristic of high sensitivity, high stability and no false action existing.
