Educational project on the design of a demonstrator with automatic pressure measurement
Résumé
In this paper, the design of a demonstrator with automatic pressure measurement is given. This work is proposed as an educational project with the joint contribution of two French teaching institutions and aims at exploiting a Pirani pressure sensor, conventionally used for very low pressure measurement, for beyond atmospheric pressure measurement. The sensor and the associated electronic interface are designed by students majoring in electronics while students majoring in computer science take in charge the software development for the automatic control of the measurement. The hardware implementation of the pressure demonstrator as well as the associated software development is presented in the paper. Within the developed interactive Graphic User Interface (GUI), three data areas are available: pressure related user command, measured pressure and temperature values in real time, and ongoing transient curves acquisition.
