Altimeter

Working Principle of Altitude Measurement Tool

In measurement, it is really needed an accuracy, accuracy, and sensitivity. Measurement using an analog barometer and altimeter often results in inaccurate measurements because of the many error factors that influence. To reduce the error factor, the altimeter and barometer are made digitally. How does a height gauge or altimeter work? There are several working principles on the altimeter, among others:

1. Barometric pressure (the most commonly used)

2. Earth magnet (with inclination angle)

3. Waves (ultra sonic or infrared, etc.)

4. The use of an altimeter is generally always followed by the use of a compass.
