- Versatile Power Options
- Operates on 5V, 12V, or 24V DC, compatible with most power adapters.
- Built-in 2A relay can directly drive connected loads.
Working Principle
The sensor uses capacitive sensing technology:
- No Liquid: A static capacitance exists between the sensor and the ground.
- With Liquid: Proximity of liquid increases the capacitance, which is processed by the control IC to determine the presence of liquid.
When the capacitance change exceeds a set threshold, the sensor outputs a signal indicating the liquid has reached the sensing point.
Applications
- Liquid level detection in small-diameter non-metallic pipes.
- Industrial monitoring of corrosive or high-temperature liquids.
- Medical and laboratory applications requiring precise liquid monitoring.
