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 5~12V 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 (5~12V), suitable for connecting various circuits and product applications.

Signal output:
This series of products is specially developed for non-metallic pipeline liquid level detection. This series of liquid level sensors are divided into three kinds of signal output interfaces, which are high and low level output interface, NPN output interface and PNP output interface; The following three models:

Wiring:
1: Brown wire(VCC) Power +5 to 24V（Power+）
2: Yellow wire: Signal out
3: Black wire: Signal selection line
4: Blue wire(GND) Ground wire(connect Power-)

PNP Output drive small relay(currents100mA) Working Principle
1:When the black wire do not connect or connect high level is normally open output;
a-When detect the liquid, transistor turns on, the relay is energized
b-When do not detect the liquid, the transistor is cut off, the relay is powered off.
2: When the black wire connect GND(connect power- 0V) is normally closed output.
a-When detect the liquid, the transistor is cut off, the relay is powered off
b-When did not detect the liquid, transistor turns on, the relay is energized



Typical Installtion for pipe:
Detector can use super glue to paste into the pipe tightly,you can also use nylon ribbon tofasten it tightly,when you install the probe, you should avoid metal parts.
The applicable pipe should be smooth surface,uniform thickness, tight material,goodinsulation non-metal pipe, like glass pipe,plastic tube, PC/PVC pipe,non-absorbent ceramic pipe,Acrylic tube, rubber pipe or rubber composites pipe:

Product Maintenance
Please keep the sensor clean, anti-corrosion and avoid collide and hit by other objects.
 
Outdoor installation should avoid the direct sunlight, away from heat and pay attention to ventilation, if the ambient temperature exceeds the rated temperature, should take the appropriate cooling protection measures.
 
When the ambient temperature is too low, use the instrument protection box or other protective equipment for antifreeze protection, and pay attention to keep the level gauge dry.
 
The sensor should be checked regularly. (The detection interval is determined by the use unit according to the specific situation).
How to Adjust Sensitivity?
From the side of the XKC-Y26-PNP non-contact level sensor, you will find an adjustment 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



Trouble shooting:
Fault condition Cause Analysis Solution
  After powered,level sensor doesn't react(water level to reach the sensor point indicator does not light, the sensitivity adjustment no response)
　		  ① Power is not connected Check and connect the power supply
 ②Power line + -  Reversed Correct wiring
 ③ The power module is damaged Replace the circuit board where the power module is located
④　Sensitivity is too low Adjust sensitivity
The indicator light is always on　  ①Sensitivity is too high   Adjust sensitivity
 ② The initialization parameter is modified abnormally   Return to factory re-initialization
 ③ The sensor has a debris or other metal parts close Clean debris, and keep a certain distance from the metal parts
