Installation
The installation of the telemetry assembly
can be divided into its mechanical place-
ment, including the connection of sensors
and transducers, finding the optimal location
of the GSM antenna and inserting the SIM
card, and setting the control parameters.
The detailed description and setting of the
individual parameters is covered in Chapter
4.
3.1.
Mechanical positioning
of the telemetry assembly
If possible, then install the assembly in a lo-
cation free of permanently condensing mois-
ture. If this cannot be avoided, then extra
care must be taken when connecting the
connectors - to tighten them (they have a
built-in O-ring). It is also advisable to treat
the GSM antenna connector with silicone
petroleum jelly or insulating self-adhesive or
self-vulcanizing tape to seal any leaks.
The telemetry assembly should not be in-
stalled in locations where the temperature is
consistently above 40
°C
, as this increases
the self-discharge of the power supply bat-
teries, resulting in a shorter battery life. Con-
versely, low temperatures below -20
°C
re-
duce the usable capacity of the batteries.
The measuring set H40(G) + water level and
temperature sensor TSH22 is usually sup-
plied with a stainless steel bracket DH40,
which also forms a hanger for the connected
sensor cable. This type of bracket is particu-
larly suitable for placing the H40(G)+TSH22
in a borehole or narrow installation pipe with
a diameter of only 50 mm.
