Level Sensor | External Non-Contact Mount | Y26 Liquid Detector

The XKC-Y26 is a sensor that detects liquid levels without touching the liquid. You attach it to the outside of a tank or pipe. This sensor signals when liquid reaches a certain point. It never makes contact with the fluid. It has an IP67 rating, meaning it's sealed against dust and moisture. Features and Benefits - No drilling needed - The sensor sticks or straps onto the container's outside. You don't need to drill holes, which prevents leaks. - Wide power range - It works with a 5-24V power supply. This makes it suitable for many industrial and hobby control systems. - Senses through materials - This capacitive sensor detects water through non-metallic materials. These include plastic, glass, or ceramic up to 20mm thick. - Reliable electronic operation - It has no moving parts to break or get stuck. This sensor provides consistent performance for a long time. Applications - Starting a pump to refill a water tank when the level gets low. - Turning on an indicator light or alarm when a waste fluid container is full. - Monitoring processes in food and beverage production where cleanliness is important. Mechanical / Float Sensors Mechanical water level sensors, often called float switches, typically use a buoyant float that moves with the liquid level. This float is connected to a switch, often a magnetic switch or a reed switch, which opens or closes an electrical circuit as the level changes. They are a straightforward way to detect water levels and signal if a tank is full or empty. While effective, they require direct contact with the liquid and can be affected by debris or viscous fluids. This product is not a mechanical float sensor. Ultrasonic Sensors (Non-Contact) Ultrasonic sensors measure liquid levels by emitting sound waves and calculating the time it takes for the waves to return after reflecting off the liquid surface. This non-contact method means they are not affected by the liquid’s properties or potential contamination. They are often used for continuous level measurement in tanks or sumps. This product uses a non-contact detection method, but it does not use ultrasonic theory to achieve this. Submersible Hydrostatic Pressure Sensors Submersible hydrostatic pressure sensors work by measuring the pressure exerted by the column of liquid above them. As the water level changes, the pressure changes, and the sensor converts this into an electrical signal. These sensors are submerged directly into the liquid and provide a continuous reading of the water depth. They are robust and suitable for various applications, but they do require direct contact with the liquid. This product is an external non-contact mount detector. Capacitive Sensors Capacitive sensors, like this Y26 Liquid Detector, work by detecting changes in capacitance caused by the presence or absence of a liquid. This specific product uses capacitance theory for its operation. It is an external non-contact mount, meaning it can detect pipeline water level without direct contact with the liquid, making it suitable for applications like pipeline water level detection. The output type is digital, providing a clear on/off signal. Optical Sensors Optical water level sensors use light to detect the presence or absence of liquid. They typically consist of an infrared LED and a phototransistor. When the sensor tip is submerged in liquid, the light is refracted away from the receiver, triggering the switch. When exposed to air, the light is reflected back to the receiver. These are often used for point level detection. This product does not operate on optical theory.
