The best altimeters to always know how high you are
In advance, the functions of an altimeter are related to extreme sports practices oriented, in any case, to users already experienced in the world of adventure, climbing, or even more minor disciplines such as skydiving. However, this device’s uses are very diverse. It can be a good ally for much more common activities available to any lover of the countryside or the mountains. As a historical note, note that the altimeter was invented in the 1920s by the German engineer Paul Kollsman. It was first used for measurements in 1929. What is it, and what is it for As is clear from its name, it is a device used for measuring altitudes. Determine the difference between your highest place and a landmark, generally sea level. They can also be described as reconverted barometers calibrated to translate pressure into altitude measurements. As can be deduced, his first assignments were linked to aviation. However, its versatility is very high at present, and it can be used for many different outdoor activities. We highlight some: skiing, climbing, hiking, mountaineering, skydiving, and aviation, as we have already mentioned. How does it work While we explain how it works, we establish different types: 1. Barometric: The most used in aviation. Use atmospheric pressure to define altitude (higher altitude, lower pressure). The higher quality versions of these types withstand climatic variations. That is, they assume climatic variation in such a way that it does not influence the measurement. They use sea level pressure (1013 hectopascals (hPa)) as a measurement parameter. Consequently, on long-distance trips, they must be calibrated periodically. They are uneven in your data with pronounced height changes. 2. Radioelectric: Also known as radar altimeters. They are more precise and faster than pressure ones. They are carried primarily by supply or firefighting aircraft that need …
