Temperature control instrument fault analysis - Database & Sql Blog Articles

Temperature control instruments are used in the industry. Jiangsu Zhixing measurement and control instruments have summarized some precautions for the use of temperature instruments. They have won unanimous praise from customers and peers in the industry. Let's share them with you.

When analyzing the temperature control instrument system failure, first pay attention to the following points:

1. The indicator value of the temperature meter system suddenly changes to the maximum or minimum, which is generally the fault of the instrument system. Because the temperature meter system measures a large lag, no sudden changes will occur. The cause of the fault at this time is mostly caused by thermocouple, thermal resistance, compensation wire breakage or transmitter amplifier failure.
2. The temperature control instrument system indicates that there is a rapid oscillation phenomenon, which is caused by improper adjustment of the control parameter PID.
3. The temperature control instrument system indicates a large and slow fluctuation, which is probably caused by a change in process operation. If the process operation does not change at that time, it is likely to be a malfunction of the instrument control system itself.

These are just some of the small recommendations for the use and maintenance of many instruments. Jiangsu Zhixing Measurement and Control Instrument is based on the highest purpose of serving customers. In the future, it will gradually present some knowledge of the use of instruments, share it with everyone, and will also Gaining other aspects of mutual benefit and mutual benefit to achieve the goal of common development and progress.
