Inductive Sensors

This lecture explores the use of inductive sensors for proximity measurement, highlighting their advantages over capacitive sensors in harsh environments with contaminants like oil and dust. The lecture delves into the construction and physical principles behind inductive sensors, explaining how they are less affected by external disturbances. It also discusses the circuitry used to measure inductance variations and the importance of frequency selection based on material properties. Additionally, the lecture covers the detection of different materials using inductive sensors and the impact of material conductivity and magnetic properties on sensor performance.
