Non-Contact Liquid Level Sensor | Stick-Type Induction | 5-24V

The XKC-Y25-V is a non-contact liquid level sensor. It runs on 5-24V and detects fluid from outside a container. This sensor works by sensing water or other liquids without direct contact. It's a simple, effective water level switch for your project. Features and Benefits - No container contact - It measures levels through the container wall. You don't need to drill holes. This prevents leaks and contamination. - Adjustable sensitivity - You can tune the sensor. It works with non-metallic containers like plastic, glass, or ceramic up to 20mm thick. - Wide 5-24V input - It connects directly to many power sources and microcontrollers. This makes it good for an Arduino project. - NPN signal output - The sensor gives a simple high/low signal. You can use it to control a pump, trigger an alarm, or activate a relay. Applications - Water tank automation - Attach it to a water tank. It can manage refilling systems or prevent overflows automatically. Installation is not complex. - Industrial fluid monitoring - Use this sensor to check levels of acids, bases, and other corrosive liquids safely. You won't risk sensor damage. - Sanitary equipment - Monitor fluids in food-grade or medical containers. The liquid must stay sterile. It works with liquids up to 100°C, including boiling water. Mechanical Ball / Rolling-Element Switches (Simple On/Off) These are straightforward tilt sensors that use a rolling element, often a metal ball, within a housing. When the sensor tilts beyond a certain angle, the ball rolls and makes contact with two electrical terminals, completing a circuit and acting as an electrical switch. This provides a simple on/off signal, indicating whether the sensor is tilted or not. They are typically used for basic tilt detection rather than precise angle measurement. The product on this page is a Stick-Type Induction Detector, not a mechanical ball type. MEMS Accelerometers (Precise Angle Measurement) MEMS (Micro-Electro-Mechanical Systems) accelerometers are sophisticated gravity sensors that measure acceleration, including the acceleration due to gravity (1g). By sensing changes in orientation relative to gravity, they can determine the tilt angle with high precision. They provide analogue or digital outputs that correspond to the exact angle of tilt across multiple axes. This allows for detailed angle measurement, unlike simple tilt switches. The Stick-Type Induction Detector described here is a switch output type, not a MEMS accelerometer. Optical Tilt Sensors Optical tilt sensors use light to detect changes in orientation. This can involve a light source and a detector, where the path of light is interrupted or reflected differently as the sensor tilts. Some designs might use a liquid surface or a pendulum to deflect the light beam. These sensors can offer good accuracy and are often used in environments where magnetic interference might affect other sensor types. The product on this page is a Non-contact Induction detector, not an optical type. Quick Comparison The product featured is a Stick-Type Induction Detector with a switch output. This differs from mechanical ball switches, which rely on physical contact, and MEMS accelerometers, which provide precise angle measurements. Optical sensors use light, whereas this product uses non-contact induction for detection. The operating voltage is DC 5-24V, and it features a durable plastic material construction. It functions as a switch, providing an on/off signal rather than continuous angle data. The Gravity Sensor The term "gravity sensor" broadly refers to any sensor that detects changes in its orientation relative to the Earth's gravitational field. This includes tilt sensors. When asking "how does a tilt sensor work" in relation to gravity, it means the sensor is designed to detect when its position changes from being level, responding to the pull of gravity. The product here is a Level Sensor Switch Detector, which implies it senses a level change. It is a non-contact induction type with a switch output.
