Accelerometer Cable Cross-Section Area

Knowing the "average" won't help. Could be anything from 2-3mm to 10-15mm, depending on application, though 4-6mm would be more common.

Best way to go is select your accelerometers & work back from that. If they're pre-wired, you've got your answer. If not, you can chose your own cable (as long as it meets the supplier's recommendations re. current carrying & screening).

Thanks for the answer. Are these values the diameters in milimeters, or are they areas in milimeter square? I'm asking because I don't know anything about the magnitude of the values either (and a 10mm diameter cable seemed thick to me for signal transmission, might be my lack of knowledge on accelerometers)

I've given the OD (in mm) of a complete insulated cable. The larger diameters I cited would only be appropriate where there was need for protection against physical damage.

The actual wire csa needed for the conductors is probably only about 0.1 or 0.2mm² - but as I said, you should check with the manufacturer or supplier of the particular devices you're going to use.

Here's one I came across from Sherborne:

The block is 30mm x 30mm x 9.5mm, so you can roughly scale the cable OD.

Yes, I'm expecting to receive an answer from the facility that has the accelerometers soon enough; I urgently needed an estimation on what magnitude it could be. Thank you a lot for the help! :)
