Description
Product Description
A liquid level sensor detects water level or liquid height and converts level changes into switch, analog, or digital signals. It is suitable for water tank monitoring, pump control, appliance water-level detection, and industrial liquid-level alarms.
Common Types
Float level switches use buoyancy to move a magnet and trigger a reed switch, offering a simple and reliable structure. Capacitive liquid level sensors can attach to the outside of non-metal containers for non-contact detection. Photoelectric level sensors are compact and accurate, often used for dry-run protection in micro pumps. Submersible level transmitters can be placed directly at the bottom of liquid for continuous depth measurement.
Parameters and Output
Common operating voltages include DC 5V, 12V, and 24V. Output can be high/low level, relay switch signal, 0-5V analog voltage, or 4-20mA current signal. When paired with controllers such as Arduino, ESP32, or STM32, water level status can be read through GPIO or analog inputs.
Application Scenarios
Suitable for water towers, pools, water purifiers, coffee machines, aquariums, sewage treatment equipment, chemical containers, and automatic refill systems. Confirm the liquid type, detection method, installation position, supply voltage, and output signal when selecting.
