This paper addresses the use of capacitive measurement principles for process instrumentation. A brief review on capacitance-based sensors to measure industrial process parameters is provided. A capacitance-to-digital conversion system developed at the Sensors Group at our Institute is presented. Applications of capacitance-based process instrumentation for moisture sensing, flow velocity determination, fill level measurement and proximity sensing are discussed in detail.
