Issues with transmitting multi-point thermal resistors using multi-core cables
Thread Content
May I ask: Have multi-point thermal resistors that are transmitted via a multi-core cable been used before? For example: 6 thermal resistors are transmitted to the junction box using DJYVP(R) 1x3x1.5 or KVVP(R) 3x1.5 cables, and from there they are sent to the DCS via DJYPVP(R) 8x3x1.5 cables. It seems that many people avoid using multi-core cables to transmit thermistor signals. I wonder what the problem is?
There is no problem; multi-core cables can transmit thermistor signals, and there are examples of this.
It’s not a big problem to use a multi-core cable for transmitting the weak resistance signal through the cable tray, right?
There’s no problem at all; feel free to use it – the cable shielding is sufficient!
