Comparison between Separated Photoelectric Liquid Level Sensors and Capacitive Liquid Level Sensors 3

The advantages of capacitive liquid level sensors include high accuracy, strong adaptability, and high reliability. However, they are sensitive to the dielectric constant and temperature of the liquid, and oxidation reactions may occur between the electrode and the liquid.

In general, separated photoelectric liquid level sensors are suitable for applications that require high transparency of liquids, while capacitive liquid level sensors are suitable for applications that are sensitive to changes in liquid dielectric constant and temperature. The selection of suitable liquid level sensors should be determined based on specific application requirements.  diode
