What gauge of wire should be used for instrument wiring, and what type of wire is considered standard? Temperature, pressure, flow rate, valves – all of these are included
It mainly depends on the distance. For small projects, 1.0 is sufficient; for larger projects, a value of 1.5 is needed when the distance is greater. Generally, DCS or computer cables are used; screen splitting is required for the main screen, and intrinsically safe cables are necessary for intrinsically safe applications
Different industries have their own regulations; search online for HG, SH, etc
Agree with the person in floor 2; the design takes distance into account. If the distance is too great and the wire diameter is too small, the wire resistance will be high, resulting in excessive voltage division, which may prevent the instrument from functioning properly.
All the instrument control cables in our company are of the KVVRP type. But I didn’t notice which ones use intrinsically safe cables. Is it okay to use cables that are not intrinsically safe?
It is mainly calculated based on the distance
I’m not a professional; I just learned this while passing by. Is there any summary table or software available?
We produce control wires for instruments; is there any demand for them?
Normally, it’s sufficient to use an instrument shielding cable with a cross-sectional area of 1.5 mm2; it’s not that complicated
I usually choose 1.5mm2; there’s no problem with that
