Equipment can be used under all climates.
Operates in extreme environments from polar zones to tropical
and equatorial areas.
For example:
- Stations from the IRAT network in the Réunion
island have recorded during the day of 12/02/1987 a rainfall
depth of 1.358mm and a total wind higher than 500 km.
- Settlement in Nepal at more than 5.000m of altitude.
Use of a double casing technology to face the environmental
constraints:
-
A ventilated exterior box with
internal thermal protection.
-
A leak-proof electronic dehydrated
box of reduced dimensions.
-
Terminal board for plug-in sensors connections
with single outlets.
-
Highly integrated electronics,
use of programmable logic circuits.
-
This helps in reducing the number of components
and increasing global reliability.
This technology for severe environment is used
in all our stations in order to ensure a very high level of
reliability and an ease of operation.
Protection reinforced :
Reduced consumption : less than 1mA for
a voltage of 5V, which leads to a small dimensions solar panel
and an operating battery for 1 month without recharge.
