Working Principle and Core Features of Capacitive Liquid Level Sensors
A capacitive liquid level sensor is a device that uses the principle of capacitance change to achieve non-contact liquid level detection. Its core working mechanism is to determine the liquid level by sensing the change in capacitance caused by the difference in dielectric constant between the liquid and air. Technical Advantages and Application Scenarios of Capacitive Liquid Level Sensors Core Technical Advantages Non-contact installation: No holes are required; it operates by attaching it to the outer wall of the container, preventing liquid contamination. It is suitable for applications with high hygiene requirements, such as medical and food processing. Typical Applications Industrial Automation: Oil tank level monitoring, chemical reactor level control, boiler drum water level measurement, etc. Supports 4-20mA analog signal output and is compatible with industrial control systems. Consumer Electronics: Water dispensers, humidifiers, coffee machines, and other home appliances, pro...
