Ring-11 Liquid Level Switch by Shenzhen Jiwei Automations Ltd.: A Leading Force in Industrial Automation
In the wave of modern industrial automation, liquid level detection devices play a vital role. Liquid level switches not only ensure the safe operation of production processes but also significantly enhance automation levels and production efficiency. As a professional liquid level switch manufacturer, Shenzhen Jiwei Automations Ltd. stands at the forefront of the industry with its deep technical expertise and continuous innovation. Its flagship product, the Ring-11 liquid level switch, has earned wide recognition and praise across industries due to its outstanding performance and exceptional quality.
Jiwei: The Driving Force Behind Industry Leadership
Shenzhen Jiwei Automations Ltd. is more than just a manufacturer — it is a pioneer in technological innovation. With ISO 9001-certified quality management, Jiwei has become a benchmark in China’s industrial measurement sector. The company has achieved several industry-firsts in China, underpinned by its powerful R&D capabilities and robust manufacturing strength.
China’s Only Manufacturer of 6-Meter Long Liquid Level Switches
In the field of ultra-long liquid level detection, most manufacturers in China are limited by technical constraints and equipment capabilities, making the mass production of 6-meter level switches extremely rare. Jiwei has overcome these challenges, becoming the only manufacturer in China capable of producing 6-meter long level switches at scale. This technology is ideal for high-level tanks, deep wells, and other specialized applications — a key competitive edge for Jiwei.
Hastelloy Material and Diverse Customization Options
Jiwei continues to expand its materials offerings by providing Hastelloy alloy liquid level switches, ideal for highly corrosive environments such as marine, chemical, and smelting industries. In addition, stainless steel switches are widely used in food, pharmaceutical, and water treatment applications due to their durability and chemical resistance. Jiwei’s material versatility ensures optimal performance even in the most demanding scenarios.
National High-Tech Enterprise Driving Innovation
Recognized as a National High-Tech Enterprise in China, Jiwei owns over 50 patents and software copyrights, demonstrating its commitment to independent innovation. Its proprietary technologies span structural design, signal processing, and material selection, guaranteeing product performance and uniqueness in the global market.
SIL Certification: Verified Functional Safety
Unlike many uncertified or unverified products on the market, Jiwei’s liquid level switches are SIL (Safety Integrity Level) certified by official Chinese regulatory bodies, fully complying with IEC 61508 and IEC 61511 standards. This makes Jiwei’s products ideal for hazardous industries such as oil & gas, chemicals, and power, ensuring operational safety and reliability.
Original Design with Full IP Ownership
Jiwei firmly rejects the use of generic molds or OEM solutions. All products are independently developed by Jiwei’s in-house engineering team, ensuring complete intellectual property ownership. Every step — from concept and prototype to mass production — is tightly controlled to guarantee high quality and stability. Choosing Jiwei means investing in authentic, original, and trustworthy products.
Ring-11 Liquid Level Switch: Core Advantages
Leveraging Jiwei’s rich technological foundation, the Ring-11 liquid level switch offers industry-leading features and performance, including:
High Sensitivity, Accurate Detection
Using advanced vibration frequency detection technology, the Ring-11 detects changes in frequency between air and liquid to determine liquid presence. Its high sensitivity design allows it to detect even thin liquid films or viscous substances, minimizing false alarms and missed detections to ensure safe, stable production processes.
Superior Corrosion Resistance with Material Customization
Jiwei enforces strict material selection standards. The Ring-11 can be customized with Hastelloy, stainless steel, and other materials upon request. Hastelloy is ideal for highly corrosive media, while stainless steel performs reliably in general industrial settings. This material flexibility meets the needs of petrochemical, pharmaceutical, and food industries.
Wide Temperature Tolerance, Stable Performance, Leading in China
The Ring-11 supports a broad operating temperature range up to 280°C, far exceeding the limits of most domestic alternatives. This makes it suitable for high-temperature steam lines and thermal oil tanks. Jiwei leads China’s market in thermal compensation and sealing technology, ensuring long-term accuracy and reliability under extreme conditions.
Multiple Output Options with NAMUR Support for Smart Integration
The Ring-11 supports a variety of output modes including relay, PNP, and NPN, and also supports the NAMUR standard, widely used in industrial automation. NAMUR outputs offer low power consumption and high interference resistance, making them ideal for hazardous or safety-critical environments. Jiwei’s in-depth integration of NAMUR functionality offers enhanced flexibility and smart automation capabilities for customers.
High Protection Grade for Harsh Environments
With an IP67 protection rating, the Ring-11 is dustproof, waterproof, and built to withstand demanding environments such as those with high moisture, dust, or vibration. Its rugged design reduces maintenance costs and system failures, extending equipment lifespan and reliability.
Broad Industry Applications
Thanks to its robust design and stable performance, the Ring-11 liquid level switch is widely used in various sectors:
- Petrochemical Industry: Monitors acids, alkalis, and flammable liquids in storage tanks and reactors, ensuring safety and preventing overflow or dry-run damage.
- Food & Beverage: Made from food-grade stainless steel compliant with hygiene standards, Ring-11 is suitable for liquids such as milk, juice, and beer, supporting strict hygiene requirements.
