Custom cable length is included as an option with many of our sensor designs. However, there are practical limits to observe. If it is possible to do, it is almost always preferable to do long cable runs with a junction box next to the sensor. With separate jumper cables running back to the instrument. A sensor with 100’ of cable permanently attached is expensive and unwieldy. If the sensor expires, all that perfectly good cable must be purchased again with the replacement. Far better to have a standard 10’ unit and 90’ of jumper cable.

Keep in mind that some conductivity instruments have upper limits on cable lengths that can be accommodated. Some are hard-pressed to handle 20’, while others can take several hundred feet. Try to determine the instrument manufacturer’s specs, which is usually simple to do.

Specify enough cable to do the job, but be careful of asking for too much. On some conductivity sensors, you could simply cut off any excess, but with unique or specialty connectors it means that the extra length must be kept, and stuffed into a too-small junction box. Making life a little more difficult.
