Help needed: instrument automation design, terminal wiring diagram
Thread Content
The content of the first image is part of the second image; what do the various elements in the image mean, and how did they come about? What are the specific steps to create a terminal wiring diagram using this diagram as a template? I would appreciate it if everyone could help me answer this.
I would like to ask what value 100 kPa corresponds to in terms of tons for a differential pressure flow meter
Let professionals do professional work; if one can’t understand this, they are 100% not from an electrical and instrumentation field.
I don’t even know what you want to know; are these all questions?
Information in the diagram: Thermal resistance signal; shield wire connected to copper busbar; cable model: ZR-DJYVP-1X3X1.5
No one can answer your question; a flow calculation sheet is necessary, as it is only with this sheet that the flow rate at a given pressure difference can be calculated.
Information in the diagram: 021-01xs – this is likely the identifier for the intermediate junction box. ABC indicates a three-wire system; the shield wire must be grounded, usually using copper bars. It should be included in the junction box. TE210101aRC: TE210101a is the part number; RC denotes a regular resistor. The cable model is ZR-DJYVP-1X3X1.5 – it is a copper-wired shielded computer cable (ZR-DJYVP), with three conductors and a wire thickness of 1.5 mm2
Take out the calculation sheet provided by the manufacturer; it contains the formulas, and once those are used, the differential pressure can be calculated. If you’re worried about making mistakes in the calculations, just ask the manufacturer to do it for you – it won’t take more than 3 minutes
Are you the technician who installed the new gauge?
It does not exactly match our institute’s standards, but it can be used as a reference
