Precautions for grounding protection of Rosemount level transmitters
Thread Content
Keywords of this article: Rosemount. http://www.myzdhcn.com/ When measuring using Rosemount level transmitters, it is necessary to ensure that the zero point of the measured potential matches the zero point of the medium, so as to prevent any errors from occurring; At the same time, proper grounding must also be carried out; this helps to prevent the generation of electric potentials caused by the fluid flowing through the pipes. Therefore, proper grounding is quite important for our measurements. Then, let me introduce the precautions for ground protection. When providing grounding protection for Rosemount level transmitters, the following points should be noted: 1. The sensor’s measurement tube, housing, shield wire, converter, and secondary instruments must all be grounded. 2. The shielding layer of secondary instruments should be grounded on the control room side. Do not ground it at multiple points, as this may introduce interference due to differences in electrical potential. 3. The grounding point of the instrument should not share the grounding of other electrical equipment; it must have a separate grounding point. The sensor of the level transmitter is mounted on a metal pipe; its grounding wire can be connected to the pipe flange as required, thereby forming a stable grounding circuit. 4. Converters and sensors must not be connected to motors or process pipelines; they should be grounded separately, with a grounding resistance of less than 10 ohms. Above, the editor introduced to you the precautions regarding the grounding protection of Rosemount level transmitters. If you have any additions or comments, please leave a message.
