Abstract

Electrical capacitance tomography（ ECT） sensor is a kind of non-contact sensor. It can realize real-time imaging without disturbing original flow field. In order to improve anti-noise property of ECT sensor

a rectangularambulatory-plane structure sensor is designed

and simulation experiment compared with rectangular ECT sensor is carried out by assessing error function and variance analysis methods. The experimental result shows that rectangular-ambulatory-plane ECT sensor has advantages of stable imaging quality and good anti-noise property.
