A three-electrode capacitive sensor structure is designed and simulated for monitoring and estimating amount and size of air bubbles in oil. The capacitive sensor consists of three electrodes that are structured by the PCB, copper sheets and vias. The oil pipe as a fluidic channel is threaded through the hole of capacitive sensor. By using that structure, air bubble inside fluidic channel can be detected in real-time monitoring. Simulations showing the change of signal in correspondence to the volume of air bubble inside oil channels are compared to the measurement to give a good idea of fabrication structure. In this measurement, this capacitive sensor can monitor an air bubble with a small size of 0.1 mm3 to 3.83 mm3. The occurring of multi air bubbles is also monitored by this capacitive sensor for distinguishing each bubble when the bubbles have a small distance among them. 2018-05-07T03:14:12Z 2018-05-07T03:14:12Z 2015 Article 2588-1140 http://repository.vnu.edu.vn/handle/VNU_123/61780 other Tập 31;Số 1 application/pdf H. : ĐHQGHN |
