This miniature non-contact liquid level sensor utilizes capacitive sensing to detect the presence and level of liquids through non-metallic container walls. Without requiring direct liquid contact, this sensor eliminates risks of corrosion, contamination, and media adhesion, making it an ideal solution for monitoring aggressive substances such as strong acids, alkalis, and toxic liquids in sealed environments.
One-Touch Smart Calibration
A simple press of the sensitivity button initiates automatic calibration within 3–5 seconds, allowing this sensor to intelligently lock the optimal sensitivity setting for the current container material and wall thickness. This one-touch feature enables rapid adaptation to containers of up to 15mm thickness without manual tuning.
Advanced Capacitive Sensing Technology
At the core of this sensor is a precision capacitive detection system. When liquid rises and approaches the sensing surface, the coupling of the liquid’s parasitic capacitance with the sensor’s static capacitance causes a measurable change. A builtin highaccuracy control IC converts this minute variation into a differential signal and analyzes it with a proprietary algorithm, triggering an output once the liquid level reaches the set threshold.
UltraCompact & Rugged Design
Measuring just 6.1mm in thickness, this miniature liquid level sensor can be easily embedded into tight spaces. Its enclosure is molded from PCV0 flameretardant material and carries an IP67 protection rating, ensuring reliable performance in harsh industrial and outdoor environments.
Broad Controller Compatibility
This liquid level sensor can be directly interfaced with popular main controllers such as Arduino, making integration into prototyping and embedded systems straightforward.
From household appliances and medical equipment to industrial liquid monitoring and chemical processing, this sensor provides a safe, noncontact method to detect liquid levels. This sensor's robust design and smart calibration make it a reliable choice for a wide range of liquidsensing applications.
