Abstract

The use of impedance spectroscopy makes it possible to identify different substances based on their different fingerprint. In industrial applications, impedance spectroscopy has the potential to monitor processes. It is a technique of simple implementation, low cost and minimally invasive. In this study, a system based on electrical impedance spectroscopy was developed, calibrated and validated. The system comprises a sensing cell, an electronics and data processing algorithms for data extraction. The system was implemented and evaluated by measuring known substances, showing promising first results. As an example of application, the ice formation process under controlled conditions was monitored. The results show the capability of the developed system to monitor processes via impedance spectroscopy.

用于流体阻抗谱分析的简易测量系统
阻抗谱的使用使得根据不同的指纹图谱来识别不同的物质成为可能。在工业应用中,阻抗谱具有监测过程的潜力。它是一种实现简单、成本低、微创的技术。在本研究中,开发了一个基于电阻抗谱的系统,并对其进行了标定和验证。该系统包括传感单元、电子器件和用于数据提取的数据处理算法。该系统通过测量已知物质来实施和评估,显示出有希望的初步结果。作为应用实例,监测了受控条件下的成冰过程。结果表明,所开发的系统具有通过阻抗谱监测过程的能力。
