Taidacent Water Tank Fish Tank Water Leak Detector Liquid Level Gauge Detection Alarm Switch DIY Electronic Water Level Sensor
Product Description
PRODUCT 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 the wall thickness of the container and realizes the true non-level of the liquid level in the closed container. Contact detection. 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 inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the distributed
capacitance on the sensor. When the liquid level slowly rises and approaches the sensor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the sensor larger, and the changed capacitance signal is then input to the control IC for signal conversion, which will change The capacitance is converted into a certain electrical signal change, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain threshold, the liquid level is considered to reach the sensing point

Installation Instructions
Installation methods of the tested container
The pasting installation method is as shown in the figure above, which can be directly pasted on the outer wall of the plastic container.
The adhesive material can be glass glue, 704 silicone, waterproof 3M double-sided tape, etc.
Precautions:
1. Do not use double-sided tape made of foam cotton.
2. The material of the container must be insulating material.
3. Try to use materials that are uniform and do not contain air interlayers, have no bubbles, do not absorb water, and do not easily change the dielectric constant as the container.
