Abstract

This study shows a new approach method of material identification system using a capacitive sensor called the multi-frequency capacitive sensor system. The material to be measured is a pure liquid of H2O. This sensor system's workings are to use the principle of EIS (Electrical Impedance Spectroscopy), in which the measured material is non-invasive or not in direct contact with the sensor. The material is put in a vessel that has been wrapped with foil paper and coated by four electrodes sensor. The new approach method used is to obtain a signal response that is a pulse signal. It has the value of the difference in voltage reduction between the output voltage and the input voltage stored by DSO (Digital Storage Oscilloscope). This study aims to get the primary signal assumed to be noise, but the desired noise. Several frequencies inputs are low frequencies, where vary from 1 kHz - 1 MHz. Therefore, the results obtained clearly show that the multi-spectral capacitive sensor system can produce the main input. This main signal is assumed to have fluctuations values of the signal response of the measured material. Also, it will be advanced signal processing that is identified quite correctly.
