Can the CS300-L be installed with more than 50 m of 16-AWG cable?

Campbell Scientific does not recommend splicing any cable into the existing cable. Splicing a cable could introduce water and electrical noise into the connection. The sensor can be ordered with longer cable lengths, and 50 m is right on the edge of the recommended length. With a cable this long, Campbell Scientific recommends measuring the sensor differentially using the following wiring conventions:

          Wire Color

              Data Logger Channel


 Diff Channel H


 Diff Channel L


 AG or Ground Symbol

 JUMPER WIRE              

 Diff Channel L to AG or Ground Symbol

In the data logger program, a differential voltage instruction needs to be used instead of a single-ended voltage instruction.
