Description
The intelligent non-contact liquid level sensor produced by trumsense precision technology 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.

Working Principle
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.

Product Elite Feature:
 1. Non-contact liquid level sensor, suitable for non-metallic container outer wall without direct contact with liquid, no corrosion by corrosive liquid such as strong acid and alkali, free from scale or other debris.
 2. Intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, can realize multi-point series connection; support high and low level output, NPN, PNP signal output and RS485 communication interface output (when selecting and manufacturer) Description can be).
 3. The detection is accurate and stable, and the boiling water level can be detected.
 4. Pure electronic circuit structure, non-mechanical working mode, stable performance and longevity.
 5. High stability, high sensitivity, strong interference ability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with all 5~24V power adapters on the market.
 6. Strong compatibility, through a variety of non-metallic containers, such as plastic, glass, ceramics, etc., the sensing distance can reach 20mm; liquid, powder, particles can be detected.
 7. Open collector output mode, wide voltage range (5~24V), suitable for connecting various circuits and product applications.

Typical Installtion for the Metal Materail container:
1) Prepare 2 rubber plugs as the tools for opening the screw hole.
2) Open 2 screw holes in high level and the low level, the hole diameter matches rubber plug size.
3) Insert the rubber plug to screw hole and fix it, examine if there’s a leakage, sealed with glue if necessary
4) Paste the level detector on the rubber, fix it with the bracket, when the glue is solid, take away the bracket, metal material installation drawing, pls see below:

How to Adjust Sensitivity?
Open the sensor back cover and adjust the sensitivity knob with a small screwdriver:
1: Clockwise rotation to increases the sensitivity of the liquid level sensor
2: Anti-clockwise rotation to decreases the sensitivity of the liquid level sensor

Finally, the back cover is covered for liquid level detection.
