The non-contact liquid level sensor is an advanced digital module that is placed on the outer surface of a non-metallic container, such as plastic or glass, and detects the presence of liquid inside by capacitive sensing. Since it does not make direct physical contact with the liquid, it can be safely used for measuring hazardous liquids such as acids, bases or toxic substances and in pressurized, airtight closed tanks. Thanks to its sensitivity adjustment, it adapts to different container thicknesses and produces a clear digital signal when liquid is detected. It is the ideal solution for food compatible water vending machines, industrial tank fullness monitoring and hygienic automation projects where the sensor is not desired to touch the water.
