In this paper the hardware design of an Applied Potential Tomograph system developed at BARC is presented. It comprised of a data acquisition unit, an interface unit and a personal computer. Data acquisition unit measures mutual impedance values between adjacent electrodes by passing sinusoidal current in different directions. The mutual impedance value along with lead configuration number and gain value are read by personal computer through interface unit. Mutual impedance values obtained from Phantom for different conductivity distributions are shown to be significantly different.
