　　I. Working Principles

　　Inductive sensors operate based on the principle of electromagnetic induction. They utilize changes in the self-inductance or mutual inductance coefficients of coils caused by measured physical quantities (such as displacement, pressure, flow rate, and vibration) to convert these non-electrical quantities into changes in voltage or current for output. When the current in the coil changes, it generates a changing magnetic field around it, and this changing magnetic field produces an induced electromotive force in nearby conductors. Inductive sensors leverage this mechanism to convert the measured non-electrical quantities into changes in inductance, which are then converted into electrical signals by a measurement circuit for output.

　　Capacitive sensors use capacitors as sensing elements to detect changes in measured physical or mechanical quantities by measuring changes in the capacitance value of the capacitor. When the distance between two conductors or the medium changes, the capacitance of the capacitor changes accordingly. Capacitive sensors monitor this change in capacitance to detect parameters such as object position, displacement, and pressure.

　　II. Performance Characteristics

　　1.Measurement Range: Inductive sensors have a relatively large measurement range, typically reaching several meters or even tens of meters. In contrast, the measurement range of capacitive sensors is relatively small, generally ranging from a few millimeters to a few tens of millimeters.

　　2.Sensitivity: Inductive sensors exhibit high sensitivity, capable of detecting minute displacements or velocity changes. In comparison, capacitive sensors require larger displacements or pressure changes to trigger detection.

　　3.Anti-interference Ability: Inductive sensors have strong inhibition against electromagnetic and radio frequency interference, demonstrating robust anti-interference capabilities. In contrast, capacitive sensors are susceptible to these interferences, exhibiting weaker anti-interference abilities.

　　4.Measurement Accuracy: Inductive sensors offer high measurement accuracy, reaching micrometer or even nanometer levels. In contrast, the measurement accuracy of capacitive sensors is relatively lower, typically at the millimeter level.

　　5.Response Speed: Inductive sensors have fast response speeds, reaching microsecond or even nanosecond levels. In contrast, the response speed of capacitive sensors is slower, generally in the millisecond range.

　　III. Application Fields

　　Inductive sensors, due to their no-moving-contact design, high reliability, long lifespan, high sensitivity, good linearity, and other characteristics, are widely used in industries such as textiles, chemical fibers, machine tools, machinery, and metallurgy for parameters measurement and control, including chain wheel tooth speed detection, chain conveyor speed and distance detection, displacement, vibration, strain, and more.

　　Capacitive sensors, with their simple structure, high temperature resistance, radiation resistance, high resolution, and good dynamic response characteristics, are widely applied in fields such as healthcare, environmental monitoring, and food processing for parameters measurement, including pressure, displacement, humidity, liquid level, and more.

　　IV. Conclusion

　　Inductive sensors and capacitive sensors exhibit significant differences in working principles, performance characteristics, and application fields. Inductive sensors, based on the principle of electromagnetic induction, offer a large measurement range, high sensitivity, strong anti-interference ability, high measurement accuracy, and fast response speeds, making them suitable for precision measurement and control in fields such as industrial automation, robotics, and aerospace. In contrast, capacitive sensors, based on the principle of capacitance change, feature a simple structure, high temperature resistance, radiation resistance, and high resolution, and are widely used in parameter measurement in fields such as healthcare, environmental monitoring, and food processing.
