The intelligent non-contact liquid level sensor produced by XKC 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 sensor (probe) is installed above and below the outer wall of the container to be tested (the high and low positions of the liquid level).
The non-metallic container does not need to be opened, and the installation is simple and does not affect the production.
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 level sensor has no special requirements on the material of the liquid medium and the container, and can be widely used.
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 final 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 the amount of change of an 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.
This series of products is specially developed for non-metallic pipeline liquid level detection.
