“…For instance, changes in the atmospheric pressure cause a deflection to the sensing membrane of a capacitive pressure sensor (CPS), which forms a parallel plate capacitor along with the silicon die and the vacuum cavity formatted in-between. Thus, research that is in line with laboratory experimentation on MEMS barometric pressure sensors [8,9]. Such sensors are nowadays accommodated in several high-end application systems (e.g., in consumer electronics, avionics, navigation, and positioning systems, etc.)…”

“…The first experiment applies to differential barometric altimetry ; that is, altitude measurements are obtained from the two separated endpoint devices (hereafter, referred to as altimeters ) and thereafter, the in‐between absolute height difference is estimated. Because ambient air pressure decreases at a standard rate as elevation increases , absolute height determination in‐between altimeters can be obtained from either the hypsometric equation given in (1) or the international barometric formula [9,31] given in (2). The former equation requires an additional measurement of the air temperature, which is considered to be of constant value in‐between altimeters; thereby illustrating an isothermal atmosphere .…”

The latter formula determines altitude in reference to the International Standard Atmosphere (ISA = 1023.25 hPa at 15°C) and hence, it is independent of temperature measurements.…”

This paper presents a training framework that applies to Micro-Electro-Mechanical-Systems (MEMS) technology. Recommendations are in line with a prototype educational platform along with an innovative set of experiments for a creative training on barometric altimetry. The proposed platform relies on a wireless sensor network system of Ethernet as well as PC-based (i.e., LabVIEW) user interface for ambient air pressure acquisition. The web user interface renders feasible the implementation of a single setup per class, while also minimizes students' occupation on software and hardware configuration activities; hence, students are concentrated on the problem solving process. The LabVIEW controlled interface advocates tutordemonstration by means of real-time graphical monitoring of the measurement procedure. The wireless system feature provides flexibility in experimentation, allowing the examination of particular sensor characteristics (related to the design of a MEMS system) that regularly require an exceptionally expensive apparatus. ß 2016 Wiley Periodicals, Inc.

“…The first disadvantage derives from the need to use the reference volume [1,8]. Compared with the invariable vacuum, the reference pressure of the air enclosed in the reference volume depends on changes in external conditions, especially changes in temperature [10].…”

This paper deals with the concept, the design and an experimental prototype of a low-cost aerometric sensor system for sport aviation. The performance of an experimental prototype of the sensor system is compared with the performance of a standard system. The possible further development of the system is also mentioned. The system presented here originates from and extends earlier basic work on an aerometric system for general aviation. The extension implements and focuses general designs from the earlier system for real use of the current system in the category of sport airplanes and gliders. The objective of the system is to reduce the cost of aircraft instrumental equipment, and to provide improved measurement performance of the aerometric system using an innovative approach of altitude measurements. In the experimental system, altitude is still determined based on the classic barometric principle. However, for measurements of atmospheric pressure, the differential pressure sensor is used primarily in combination with a low-cost absolute pressure sensor, which also measures in a differential mode.
