SOND FOR ATMOSPHERIC MEASUREMENTS

摘要

The prior art includes, for example meteorological and radiosondes, which are used to measure the prevailing atmospheric conditions. This publication discloses a sonde for sondes and a sonde. When a sonde rises to the cold layers of the atmosphere, its temperature drops to about -50 °C. The batteries used in the sonde must be able to supply the sonde's electronics with the power they require, even in such conditions. The invention exploits the fact that the soundings carried out using sondes are of a quite short duration. According to the invention, the cooling of the batteries (2) is slowed and delayed by bringing them into thermal contact with a phase-transition substance (3). The phase-transition substance is a substance in which a phase transition takes place when the temperature changes from the temperature of the storage of the arrangement or sonde to the temperature of the measuring environment. The phase-transition substance (3) can be, for example, water, which prevents the temperature of the battery (2) from dropping below 0 °C, until the water has frozen.
