Sensing Cable

This drawing represents a simulated X-Connector application. For the purposes

of our example, each piece of sensing cable is 100 feet long and the cable’s

resistance is 2.8 ohms/foot. In a distance-read application, an SD-Z simulates

50 feet (15.24m) of cable and each branch of a X-Connector simulates 50 feet

(15.24m) of cable. The diagram shows you how a distance-read system will

calculate the distance at various points along the application.

All of RLE’s orange sensing cable has a resistance of 2.8 ohms/foot. If your

sensing cable’s resistance is 4 ohms/foot, then the X-Connector’s calculations

will be slightly different. At 4 ohms/foot, the X-Connector simulates 35 feet

(10.67m) of cable between branches; 105 feet (32.0m) total per X-Connector.

Please verify the resistance of your leak detection cable before programming

your controller. If you have questions about the resistance of your cable, refer

to the cable’s data sheet.
