I would like to ask how to choose the type of instrument cable? ?
Thread Content
For transmitters, control valves, thermocouples, thermal resistors, etc., how should their models be selected? Are there any guidelines? There seem to be many types when searching on Baidu; could someone with experience advise me on how to choose?
The load on these instruments is not high, so a copper wire with a diameter of around 1.5 mm is sufficient; double-core shielded wire should be used for transmitters, while three-core cables are appropriate for thermal resistors.
kvvp, kvvrp, djypvp, djypvrp – any of these will work; wire diameters of 1.0 and 1.5 are both acceptable.
You’re welcome; feel free to contact me if you need anything. 13637019850 Xiao Wang
