72 Integrated Sensor System
Sensor Installation Overview
This section provides the procedures to install the sensors,
wire paths, and valve boxes used to connect the sensors to
the ISDL-2400 Data Logger.
Sensors
On a map of each hole, mark the location of the ISDL-2400
based on the site survey. Determine the exact locations
of the sensors that will provide eff ective soil monitoring
coverage.
Record sensor location to avoid damage when
aerifying greens.
Two sensors per location are recommended; a top
sensor to monitor the root zone and a lower sensor to
monitor salinity conditions.
NOTE: Sensors must be addressed before installation.
Prior to burial, connect each sensor one at a time to
the data logger and take a reading to verify operation.
These procedures are found in the Programming the
ISDL-2400 Data Logger section of the manual, pp.18-
22.
Wire Paths
One or two wire paths, one for Channel 1 and one for
Channel 2, can be installed to accommodate up to 18
sensors (9 per channel). The distance between the ISDL and
the furthest sensor cannot exceed 300 feet. Use three-
conductor AWG-18 gauge irrigation cable.
Valve Boxes
For future access, it is recommended that valve boxes be
used to contain the sensor cable and wire path connections.
