Overview The intelligent non-contact liquid level sensor (hereinafter referred to as the liquid level sensor) adopts advanced signal processing technology and high-speed signal processing chip, which breaks through the influence of container wall thickness and realizes a true non-contact type of liquid level height in a closed container Detection. The liquid level sensor (probe) is installed on the upper and lower sides of the outer wall of the container to be measured (the high and lowlevels of the liquid level). The non-metallic container does not need to be opened, and the installation is simple and does not affect production. It can detect the liquid level of various liquid toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers. The liquid level sensor has no special requirements for the material of the liquid medium and the container, and can be widely used. PRO RANGE-Y26A-XXX series products are specially developed for nonmetallic pipeline liquid level detection. This series of liquid level sensors are divided into three signal output control methods: high and low level output interfaces, NPN output interfaces, and PNP output interfaces; The signal output mode corresponds to the following three models: Serial number 1 2 3 type number XKC-Y26A-V XKC-Y26A-NPN XKC-Y26A-PNP signal interface High and low level output interface NPN output interface PNP output interface 2nd.Product Features 1. PRO RANGE-Y26A-XXX non-contact liquid level sensor is suitable for all kinds of non-metal containers. The product detects the liquid through the detection signal through the non-metal container and the outer wall of the pipeline, without direct contact with the liquid. It is corroded by strong acids and alkalis and other corrosive liquids, and is not affected by scale or other debris, and it can be completed to detect whether there is liquid inside the container or pipeline. 2. Product design intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, can realize multi-point series connection control mode. It can support high and low level output, NPN, PNP signal output control (please refer to the manufacturer's instructions when selecting the model). 3. The detection liquid level is accurate and stable, and cold, hot and boiling liquids can be detected. 4. Pure electronic circuit structure, non-mechanical working mode, stable performance and long-lasting service life. 5. High stability, high sensitivity, strong anti-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. Wide range of application, strong sensing ability, can penetrate and detect the liquid level in various non-metallic containers and pipes, such as plastic, glass, ceramics and other containers. The thickness of the sensing pipe wall can reach 20mm; it can be applied to various curved surfaces., Arc, cylindrical and other irregular containers or pipeline liquid level detection. 7. Wide voltage range (5~24V), suitable for connecting various circuits and product applications 3rd.Product Applications The intelligent non-contact liquid level sensor uses the inductive capacitance of water to detect the presence of liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the presence of 2 / 10 distributed capacitance on the sensor. When the liquid level is slow When the sensor is slowly raised, the parasitic capacitance of the liquid will be coupled to the static capacitance of the sensor, making the capacitance value of the sensor larger. The changed capacitance signal is then input to the control IC for signal conversion, and the changed capacitance is converted into a circuit signal When the amount of change exceeds a certain threshold, it is judged that the liquid level has reached the sensing point. 4th.Product parameter Project name Product model Supply voltageVin Output mode electric current The output voltagehigh pulse The output voltagelow pulse The output current Response time Working temperature Applicable pipe diameter range Parameters PRO RANGE-Y26A-PNP DC 5-12V) DC 24V Switch quantity (high pulse effective) 5mA Vin 0V 100mA 500mS -20~105 Outer diameter 5mm~10mm Liquid level accuracy humidity Material Waterproof performance Safety standard certification Environmental protection certification ±1.5mm 5%~100% PC V0 Fireproof material IP67 CE ROHS-2.0 5th.product selection PNP output interface--Model: PRO RANGE-Y26A-PNP (DC 5-12V) PNP output interface----Model: PRO RANGE-Y26A-PNP (DC24V) 6th.Installation method 3 / 10 . Pull open the shrapnel . Pull the shrapnel and put the water pipe between the two shrapnels . Just let go of the shrapnel After installation, the effect is as follows note: 1. This product is suitable for pipes with an outer diameter of 5mm10mm, and the maximum shall not exceed11mm 2. The maximum opening angle of the spring leaf shall not exceed 60° 7th. Sensitivity adjustment: If the non-contact liquid level sensor cannot detect or the detected liquid level deviates from the Y26A sensor, The sensitivity knob can be adjusted with a small screwdriver. Setting method: 1. Turn counterclockwise to increase sensitivity. 2. Turn clockwise to lower the sensitivity. 4 / 10 8th.

When the dynamic viscosity is greater than 30mPaS, it cannot be measured because a large amount of 7 / 10 liquid adheres to the container wall. (2) Note: As the temperature increases, the viscosity decreases, and most high-viscosity liquids are more affected by temperature. Therefore, pay attention to the influence of liquid temperature when measuring viscous liquids. (3) Pay attention to keeping the level gauge clean, try to prevent corrosion and avoid violent collisions and blows from other objects. (4) During outdoor installation, avoid direct sunlight and rainwater directly flowing to the main body of the level gauge, and keep away from high heat sources and pay attention to ventilation. If the ambient temperature exceeds the rated temperature, corresponding cooling protection measures should be taken. (5) When the ambient temperature is lower than the normal operating temperature range of the level gauge, an instrument protection box or other protective rain cap devices can be used for antifreeze protection, and pay attention to keeping the level gauge dry. The sensor should be regularly maintained and inspected. (The detection time interval is determined by the use unit according to the specific situation). 11th.Troubleshooting: Fault status Analyze the reasons Problem solving measures After the liquid level sensor is The power cord is not connected Check and connect the power energized, there is no response The positive and negative ends of Correct wiring (the indicator light does not the power cord are reversed light when the water level The power module is damaged Replace the circuit board where the reaches the sensing point, and power module is located the sensitivity adjustment has Sensitivity is too low Adjust the sensitivity to the no response) appropriate gear The indicator light keeps on Sensitivity grade is too high Adjust the sensitivity to the appropriate grade The initialization parameters are Return to the factory to reinitialize abnormally modified The sensor has debris or other metal Clean up debris and keep a certain parts close to it distance from metal parts 12th.Product warranty terms and instructions (A).
