调节仪表及其传感器用于对生产过程中的液位、温度、压力等工艺参数实行监视和控制,当仪表指示发生明显偏差时,势必影响生产的顺利进行.面对备件短缺又要急需排除故障的对立矛盾,笔者采用模拟传感器的方式诊断故障,实践证明是一种取材容易、操作简 Regulating instrument and its sensors are used to monitor and control process parameters such as liquid level, temperature and pressure in the production process, which will inevitably affect the smooth production when the instrumentation is obviously deviated. In the face of the shortage of spare parts, it is in urgent need of troubleshooting The contradiction between the contradiction, the author uses the analog sensor fault diagnosis, practice proved to be a drawn easy, simple operation
