Abstract

The purpose of the research is to design and make an interdigital capacitor sensor (IDC) in order to pursue the measurements of permittivity of crude oil.
The scope of our research is to design and make an interdigital capacitor sensor, to perform the calibration of the sensor, to make the measurements of permittivity of the available crude oil samples, and to compare the obtained data with the ones available in the literature.
The sensor is fabricated in the ITS Instrumentation laboratory with the use of Printed Circuit Board (PCB) technology. It measures the capacity of fluid being under the investigation.
The capacitance measurements were performed using the PM 6303 A RCL meter at the frequency of 1 kHz. The IDC is directly connected to the instrument via test cable with Kelvin clips. The measurement were performed for one fixed frequency of 1 kHz at room temperature of 25 ℃ and humidity of the air of 84%.
The measurements of permittivity were performed for three samples of crude oil. As a result we obtained a reliable value of permittivity only for the sample one of crude oil. The result is as it follows: 20∙10−12 Fm with the total relative error of 8 percent. The table values of permittivity of crude oils are between 19,7∙10−12 Fm and 21,5∙10−12 Fm for the measurement performed at 1 kHz frequency [12] (depends on the sample). The permittivity obtained in this experiment fits in this brackets.
Since the sensor is capable of differentiate of various samples of crude oil and its cost of production is relatively low it could be put into a good use in the research of heating crude oil by microwave energy.
