Characterisation of Liquid Properties by Electrical Capacitance Tomography Sensor for Security Applications

摘要：

The ECT sensor based on electrical permittivity measurements is presented which may be applied to security application for contactless detection of flammable and explosive liquid. The structure, geometry and size of ECT sensor are discussed in this paper; two types of capacitance sensor are designed and compared. COMSOL simulation software is used to evaluate the performance of designed sensor. An impedance analyzer is used to measure the capacitance between each electrode pair. Results analysis is provided, the feasibility of ECT sensor using in liquid testing for security application is proved at the conclusion part.
