Hi everyone,
I work in installation of water treatment plant and have to select a cable for transmitting 4 - 20 mA analog signal from pressure sensor to control panel over 30 m. In the given specification of the client, it has been mentioned to use 2 wire system.
In a supplier catalog of analog signal transmitting cable, there are several cross section areas that can be selected.
How do I select correct cross section area?
What are the parameters I should consider selecting in the cross section area (for example, for power supply cable, we have to consider load current grouping factor, location, temperature etc. and have to use BS Code to select proper cross section area)?
I would be grateful if someone could assist me with this.
Thanks & regards,
Kaushika
