Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of capacitive bin level switch in China. Welcome to buy high quality capacitive bin level switch at competitive price from our factory. We also accept customized orders.
The HNL60-A Capacitive Bin Level Switch is a high-performance point-level detection device engineered with intelligent frequency scanning technology, ideal for both sanitary and industrial applications. Designed to reliably detect a wide range of media, this switch combines precision, durability, and flexibility to meet the demands of food processing, pharmaceutical, chemical, and storage industries.
Crafted with food-grade PEEK Natura and 316L (1.4404) wetted parts, the switch features a surface roughness of Ra ≤ 0.8 μm, complying with sanitary standards and ensuring no contamination. It operates stably within a media temperature range of -20~80℃, with ±1mm hysteresis and repeatability for accurate detection, paired with a fast response time (0.1s typical, 0.2s max) and adjustable damping time (0~10s) to adapt to different media characteristics.
Offering versatile configurations, the switch supports customizable probe lengths (30mm, 35mm, 50mm, 100mm, or custom) and flexible connections: M12 aviation plug or direct cable outlet (1M/2M). It provides PNP/NPN output options and normally open (NO)/normally closed (NC) switch logic, compatible with 12~30VDC power supply. Equipped with ED sealing and compliant with EN61326 EMC standards (when installed in sealed metal tanks), it ensures reliable performance in diverse environments.
The HNL60-A Capacitive Bin Level Switch integrates user-centric design with technical excellence, enabling easy installation via G1/2 thread and seamless integration into existing systems. Whether for sanitary fluid monitoring in food production or industrial bin level control in chemical storage, this switch delivers consistent, low-maintenance performance-making it a trusted choice for businesses seeking precision and compliance in level detection.

Value / Description |

Measurement Principle |
The HNL60-A capacitive level switch is based on the principle that capacitance changes with the dielectric constant of the medium. The probe and the container wall (or the built-in reference electrode) form the two poles of the capacitor. When the liquid level rises, the capacitance changes abruptly as the high-dielectric-constant liquid (such as water with a dielectric constant of approximately 80) replaces the low-dielectric-constant air (with a dielectric constant of approximately 1). The built-in electronic circuitry detects this change, and when a preset threshold is reached, it triggers the switch to activate, outputting an on/off signal. |
