Ten tips for temperature transmitter grounding

The correct grounding method of the temperature transmitter, the user will always have many factors in the application process, the correct use of the instrument can reduce many unnecessary troubles in the later use process. Today, Xiaobian gives you a detailed introduction to the top ten tips for grounding the temperature transmitter.

1, the control system AC power should come from a separate system, separate from other equipment and use;

2, the power supply should be designed to take into account the impact of the initial current, at least 10 cycles;

3, the control system AC grounding should be established on the isolation transformer or UPS, or in the vicinity of the temperature transmitter;

4, the control system workstation AC power should use a special socket;

5. When connecting several I/O interface adapters for field device power supply, the isolation grid should be used;

6, the control system AC power should be supplied by the isolation transformer or UPS;

7. When the AC and DC inputs are connected to the same terminal block, the terminal block must be marked with the appropriate warning label;

8, AC grounding wire should be equal to or larger than the current carrying line model;

9. Reserve an extra line or use a terminal box to provide test points.

10. The resistance of the grounding system must be tested to ensure that the grounding meets the requirements of the control system manufacturer. In fact, the above tips are also used in balancing flow meters.

The above are the top ten tips for grounding the temperature transmitter. I hope it will help everyone.
