What are the different uses of the Barometer altimeter?
The altimeter barometer, also known as a barometric or pressure altimeter, is used to measure air pressure, which can help the user predict short -term weather changes and altitude. These devices are commonly used by tourists, pilots and operators of meteorological stations who need both types of information. The Altimeter Barometer technology can be found in watches, global positioning devices (GPS), aircraft instrumentation and weather balloons using radiosond equipment that perform measurements in the Earth's atmosphere.
recreational use
Tourists and climbers often use barometer altimeters with topographic maps to determine their location using the altimeter settings. As one moves higher above the sea level, the air pressure decreases; The barometer in the device can measure these changes and provide user height on the basis of a reference point, usually sea levels. However, changes in the weather may also cause to increase or drop air pressure so that measurement altitudeThe heights are really accurate only when the weather is consistent. For example, a rapid drop in air pressure suggests that a low -pressure system is approaching. This type of change is often associated with rain and other bad weather, so a drop in pressure suggests that a tourist or caravan should find shelter.
Barometer altimeters are commonly found in sports watches, GPS hand equipment and similar tools. GPS/barometer hybrid altimeters are a popular option for outdoor activities, because unlike watches with similar manual models, users often allow users to display both height and weather functions. GPS is not always accurate in terms of the altitude of the user, and it requires that information about the sky is received, the barometer provides backup values of altitude. Such devices often allow users to maintain their routes or at least regularlyto record altitudes.
Despite the technological advantages of larger GPS devices, sports watches with Altimeter also have its advantages. For one they are light and hands free, so tourists or climbers can consider them more comfortable. Most of them are also sufficiently resistant to endure the exposure of water and other elements common in outdoor settings. In addition to being used in hiking and other outdoor activities at the level, hanging gliders, paraglides also often use altimeters of the wrist barometers.
commercial and professional use
Flight regulations require that many aircraft have an instrument that provides an altitude of the aircraft at a given moment, and usually the barometer altimeters are used because GPS values are not accurate enough. The altimeter readings are usually based on the barometric pressure of the outer air compared to the reference point on the sea level. Changes in weather conditions require to drinkThey modified their altimeter because low -pressure air mass can affect values. Commercial and military aircraft have radar altimeters that monitor the altitude by issuing radio signals that reflect from the ground and back to the aircraft receiver, giving the distance between the plane and the surface of the ground rather than the height above the sea.
National Ocean and Atmospheric Administration (NOAA), an American government agency that operates weather stations around the world, uses radiosond equipment in the weather balloons. These are tools that record and transmit temperature, humidity, air pressure and altitude value. Baromerová altari are often included in those devices that carry out readings at specific altitudes.
Collection and use of Barometer Altimeter
There are different products of products for those who look it to buy their own barometer altimeter and a wide range of features can be a bit of a skillful. Factors that need to be considered in the pendingUPUs may include the extent of the altitude that the device can measure, increments in which measurements, alarms of weather forecasts and style or materials of the device. People who plan to use hiking or orientation devices may want devices that also include a compass, thermometer, GPS or other functions. Some models can be connected to a computer so the measurement can be downloaded and saved.
Because when using high -rise and other navigation devices, there is a learning curve, it is a good idea for someone who first uses for the first time in a well -known area than it sets out on a journey where it is more important that the values are accurate and interpreted correctly. New users should exercise settings and calibration of the device and use any other features they may need. For longer trips it is always good to bring Conventional Compass together for basic directional information.
