Dynamic Performance Improvement of ERT System

Absrrucl- Elecfrical resistance tomography (ERT) is the emhranchment of Process tomogmghy lPr) .In this poper the bottleneck o/ .system real-time peformance is analysed. The dynamic performance qf sustern can he improved by increasing the signal frequenq, lqing the hand pass jilter (BPF) parallel and replacing the low pays filler (LPF) used to obtain the umplifude information by digiral measurement method Bared on these unuljses an improved ERT.yy.stem ic daigned, and a method ofpeak value meusuremmt used to obtuin the amplifude of measurement signul is broughtfbncard.
