7. Installation
If you are programming your data logger with
Short Cut
, skip
(p. 9) and
10).
Short Cut
does this work for you. See
(p. 2) for a
Short Cut
tutorial.
7.1 Siting
Install the CS225 directly in the medium that is to be measured. The types of medium that can be
measured are varied, including soils, roadbeds, and water. To make the most representative
measurement, it is important that consistent contact be made between the temperature profiler
and the medium.
The CS225 consists of the lead cable and the sensor array. The lead cable length is the length
between the data logger and sensor array. The sensor array length is the length of cable that
incorporates all temperature sensors in their specified configuration. The installation position of
the string and its measurement points are referenced from the first sensor position at the end of
the sensor array. This information is needed for the sensor configuration process.
7.2 Mounting
Orient and secure the CS225 in the measurement medium. Keep materials removed during
installation and use that material as backfill.
If a burial depth is required for each temperature sensor, you need to know the length of the
sensor array, the “measurement from end” metadata of each sensor in the array, and any offset
used during installation of the string. You will also need to calculate the depth of each
temperature sensor.
NOTE:
The furthest temperature point from the data logger (or the temperature point at the end of
the string) is addressed starting at ‘1’. Each temperature point going up the string towards the
data logger changes by one address number/letter.
Orient the lead cable of the CS225 towards the data logger to avoid loops or strain on the cable.
Also use a suitable trench or conduit to protect the signal and power cable from damage.
