摘要：
In this paper, characterization of sensitive contact-less coplanar capacitive liquid level sensors realized by polymer thick film technology is presented. It was found out that polymer thick film coplanar capacitive sensors are suitable for use in liquid level sensing application realized by contactless sensing method. Principle of measurement by using contact-less capacitive sensing method and performance of realized liquid level sensors are described in this paper. Design optimization of various geometric dimension of comb sensor structures was compared and analyzed for easy construction of very sensitive contact-less coplanar capacitive liquid level sensor. Thick film coplanar capacitive sensor is suitable, cost effective and reusable alternative for contact-less level measurement of various liquids with different dielectric constant.
