Virtual Capacitive Sensor System

摘要

In this paper construction of capacitive sensor virtual system is discussed. Capacitive sensors can be used to measure displacement, as its capacitance changes with the movement of the examined object. The structure, principles and characteristics of capacitive sensors are introduced in the paper. Virtual measurement system is constructed using capacitive sensors from Feedback and ELVIS II hardware platform of National Instruments. The software controlling the system is developed in Lab VIEW environment. Working algorithm for describing execution of the system is synthesized. Virtual capacitive transducer system is built with educational purposes.
