Q: Do I need to run shielded cable or can I run 18-4 with the KCD-W-V CO2 sensor you sell?

Here are some of the parameters we were given to help find the right solution:

  • It’s for a retail facility (upper and lower levels).
  • Between 48-60 inches.
  • High voltage.
  • The engineers for the project had specific requirements for IAQ.

So what did the Kele Tech Team suggest? DEFINITELY run shielded cable!

Shielding not only reduces signaling impacts but it also reduces electrical noise and lowers electromagnetic radiation. Plus, it protects people and surrounding machinery. So in this type of application—shielded cable is the way to go. Running shielded cable will guarantee no issues and in our opinion, it can be better to err on the side of caution when there are a lot of moving parts.

The Kele KCD Series carbon dioxide sensor was designed to offer an economical, reliable, non-dispersive infrared carbon dioxide sensor. The KCD carbon dioxide detector measures environmental CO2 levels for use in demand-controlled ventilation, air-quality monitoring, and other BAS and HVAC applications in accordance with ASHRAE standards. Fully isolated voltage analog outputs and convenient flying leads on the wall mount make installation both simple and trouble-free. The analog output is available in 0-10 Volt DC or 4-20 mA, over the industry standard 0-2000 ppm CO2 range.
