3.5mm Stereo Plug Wiring
5TE sensors used with Decagon loggers come with a 3.5mm
“stereo plug” connector. The stereo plug allows for rapid con-
nection directly to Decagon’s Em50 and Em50R dataloggers
and to the hand-held ProCheck readers. Below is a diagram
showing the wiring configuration for this connector.
Extending Sensor Cables
Decagon supplies 10-foot (3m) and 50-foot (15.25m)
extension cables for use with the stereo plug type 5TE
sensors. You can safely connect up to four of the 50-foot
cables without signal attenuation. For field applications, it is
critical
to seal the connections from the elements to maintain
a good connection and to prevent corrosion. It is imperative
that these connections are checked
before
the sensor is
buried. On the Decagon website you can access a step by step
photo tutorial of how to seal the connection. To access this
