Soil Water Content Profile Probes

7. Installation

Several configurations are possible when using the EnviroSMART

/ EasyAG

Probes with Campbell Scientific dataloggers. Among those configuration are the

following:

Option 1 (Preferred)

Device

Function

Probe Output scaled frequency

Datalogger Store scaled frequency, calculate and store water content

Option 2

Device

Function

Probe Output water content

Datalogger Store water content

Option 1 allows for use of data in Sentek’s Irrimax Software, which allows for

application of new soil calibrations after data are collected. Option 1 is used for

the purposes of this manual.

Refer to the installation manual published for each probe for information on

access tube installation. Appendix A addresses probe normalization.

8. Probe Wiring

A very small flat-point screw driver is used to open the gates of the

EnviroSMART

terminals before insertion of wires. Tighten the gate screws

after inserting wires.
