Taidacent Non Contact Liquid Level Sensor Contactless Water Tank Water Level Sensor for Tank Water Level Control with Low and High Level Output

The intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip to break through the influence of the wall thickness of the container and realize the true non-contact detection of the liquid level in the closed container. The liquid level of various toxic substances, strong acids, strong alkalis and various liquids in the high-pressure closed container can be detected. The liquid to be tested is required to be electrically conductive, the contact surface is non-metal, and the pipe is easy to install and can be widely used. High and low level output: If there is induction, the output is high level; no induction, the output is low level. Specially designed for non-metallic pipe liquid level detection You can adjust sensitivity: Remove the plastic cover of the sensors and turn the very small screw, clockwise decrease sensitivity, counter clockwise to increase the sensitivity. The intelligent non-contact liquid level sensor uses the sensing capacitance of water to detect the presence of liquid.
When there is no liquid approaching the sensor, the sensor has a certain static capacitance due to the distributed capacitance.
When the liquid level slowly rises close to the inductor, the parasitic capacitance of the liquid will be coupled to the static capacitor, causing the capacitance of the inductor to become larger.
The changed capacitance signal is then input to the control IC for signal conversion, which will change.
The capacitance is converted into a certain amount of change in the electrical signal, and then a certain algorithm detects and judges the degree of the change.
When the amount of change exceeds a certain threshold, the liquid level is considered to reach the sensing point.
