If your water tank needs to detect the liquid level, but it cannot open a hole due to structure, a capacitive sensor can be used. Capacitive level measurement D2CS-H needs to be closed to the outer wall of the container to detect. Due to the influence of impurities, fouling, corrosion and other factors, the capacitive sensor can detect the liquid level without contacting the liquid. Usually the measured liquid contains impurities, the float sensor is not suitable for use. Water level capacitive sensor D2CS-H is a non-contact type sensor. Because of its easy installation, it is widely used in medical, household appliances and other industries.
