Product Description
1, Product overview
The intelligent non-contact liquid level sensor (hereinafter referred to as the liquid level sensor) adopts advanced signal processing technology and high-tech integrated chip, which breaks through the traditional technology
The real non-contact detection of the liquid level in the closed container is realized. The liquid level sensor (probe) is installed on the outer wall of the tested container
Above and below (high and low level of liquid level), non-metallic containers do not need to open holes, and the installation is simple and does not affect the production. It can be used in high pressure closed container
All kinds of toxic substances, strong acid, strong alkali and liquid level detection. The liquid level sensor has no special requirements for the material of liquid medium and container, and can be widely used
General use.
2, Product features
The non-contact liquid level sensor is suitable for the outer wall of non-metallic containers without direct contact with the liquid and will not be corroded by corrosive liquid such as strong acid and alkali
Corrosion, not affected by scale or other debris.
The detection is accurate and stable, and the boiling water level can be detected.
Pure electronic circuit structure, non mechanical working mode, stable performance and long service life.
High stability, high sensitivity, strong anti-interference ability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference for compatibility
5V power adapter on the market.
Strong compatibility, through a variety of non-metallic containers, such as plastic, glass, ceramics and other containers, sensing distance up to 5mm; liquid, powder
Particles can be detected.
High and low level output mode, suitable for connecting various circuits and product applications.
3, How it works
The intelligent non-contact liquid level sensor uses the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor will stop working
Because of the distributed capacitance, the inductor has a certain static capacitance to the ground. When the liquid level slowly rises close to the inductor, the parasitic capacitance of the liquid will decrease
It will be coupled to the static capacitance to make the final capacitance value of the inductor larger, and the changed capacitance signal will be input to the control IC for signal conversion to change the capacitance value
The capacitance is converted into the change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of the change
When the threshold is set, the liquid level is considered to reach the sensing point
5, Application conditions
(1) Input voltage requirements
The input voltage of the non-contact liquid level sensor is DC 5V, and the ripple and noise voltage of the input voltage are less than 100mvp-p. Ripple and
Noise voltage is the sum of peak to peak voltage of fingerprint wave and peak to peak noise. When using this product, users should first confirm the stability and ripple of power supply voltage
And the noise voltage is less than 100mvp-p. Unstable power supply voltage or excessive ripple and noise voltage may affect the stability of the sensor. (2) Sensitivity
The factory setting standard of xkc-y23-npn non-contact liquid level sensor is: use the sensor to measure the thickness of 5mm acrylic water tank at room temperature
Water level, the sensor is attached to the outer wall of the water tank, and the water level line just rises to ± 3mm near the center line of the two screw holes of the horizontal alignment sensor. The signal line level of the sensor
There is a jump.
The sensitivity of capacitive liquid level sensor to the water level of vessels with different materials and thickness is different. Contact the manufacturer and factory before the user purchases in batch
The sensitivity parameters of the factory can be set according to different user conditions.
6, Clearance requirements between contact surface of sensor (or probe) and outer wall of vessel
It is better to use AB or its safe and solid resistant glue to tightly paste the contact surface of sensor (or probe) and the outer wall of the container. If special requirements are required, the clearance shall be low
It is better to have no gap when the distance is less than 0.5mm, otherwise the measurement accuracy may be affected.
