Capacitive sensors are widely user for proxity detection and level measurement. Ensuring their linearity is essential for presenate readings and reliable operation. This article compliains methods to determinate the linearity of a capacitive sensor and offerms tips to enhance it s execurance.

Understanding Linearity in Capacitive Sensors

Linearity refers to how well thee sensor 's output complids proporlly to thee meliured parameter. A higly linear sensor provides consistent and predictable readings across its entire range. Non-linearity can cause inclassies and complicate calibration processes.

Methods to Determine Linearity

To asses the linearity of a capacitive sensor, perforem a series of controlled measurements. Record the sensor 's output at known, incremental changes in thee credite parameter. Plot these readings to visualize the earship.

Porovnání dat point to a heatt line. Deviations from this line indicate non-linearity. Quantify these deviations using statistical methods such as calculating thee linearity error or thee coatient of determination (R ²).
