The CQRobot non-contact liquid level sensor realizes non-contact detection of the liquid level in a closed container. It adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness. It is simple to install and easy to use, and can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers.. The principle is to use 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 existence of distributed capacitance on the sensor. When the liquid level slowly rises and approaches In the case of an inductor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the inductor larger.. The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain amount It is considered that the liquid level has reached the sensing point when the threshold is reached.. High stability, high sensitivity, strong interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, strong compatibility, penetration of various non-metallic containers, such as plastic, glass, For ceramics and other containers, the sensing distance can reach more than 12mm liquid, powder, and particulate matter can be detected.. The sensor comes with 2 DIP switches, the right DIP switch controls the output voltage high level of the signal terminal green line when the DIP switch is dialed up, the high level is 5V when the DIP switch is facing When dialing down, the high level is 3.3V. Compatible with Arduino, Raspberry Pi and Other Motherboards..

Narrow 2 or 3 beam width for applications with limited measurement space. Fail-safe intelligence and diagnostic feedback for simple troubleshooting. PVDF transducer and NEMA 4X polycarbonate enclosure for corrosive liquids.

Continuous non-contact level measurement up to 49.2 1.25m. 4-20 mA output for longer signal distances up to 1000' 300m. Configuration is fast and easy via WebCal software and USB adapter. Narrow 2 beam width and short 2 dead band optimized for small tanks. Automatic temperature compensation for accurate measurement.

POWERFUL FUNCTIONS -- The ultrasonic level gauge transmits wirelessly within 100 meters of an open area. It can detect the height of the page in the tank, the temperature in the relevant area, the over-limit alarm in the tank, and record the minimummaximum value of the tank body level.. OVER-LIMIT ALARM -- When the water level sensor crosses the upper or lower limit of the water level, it will automatically alarm. The upper and lower limit water level alarm height can be set according to the needs of use. The over-limit buzzer alarm will last for 120 seconds.. MULTIFUNCTIONAL -- The Water Gauge Tank sensor has a 3.3-inch LCD display that can display the monitored temperature and water level of the water tank. There is also a temperature detection function, which displays the indoor and water tank temperature or can be switched.. WARM TIPS -- The Depth Level Meter Sensor receiver can stand on the table or hung on the wall. The liquid level sensor can be installed on the top of the water tank to monitor the liquid level. When the sensor is installed, keep at least 0.5m away from the water surface Please note that it is not waterproof and please avoid water when installing it outdoors water will easily lead to rust.. SCOPE OF APPLICATION -- The ultrasonic liquid level sensor can be used for the water level test of all non-corrosive liquids..
