Jiwei Ring-11: The ‘King of Certificates’ in Tuning Fork Level Switches for Ultimate Safety and Reliability

In the field of industrial automation, especially in liquid level measurement involving hazardous media and high-risk environments, a seemingly simple instrument can hide immense power—or fatal risks. Choosing the right level switch is not just about matching functionality; it is a comprehensive consideration of product safety, reliability, and international compliance.

When it comes to these considerations, a “certificate” becomes a hard standard for measuring a product’s true value. Yet in today’s mixed market, the authenticity, authority, and significance of certificates are often overlooked or misused.

Today, we focus on a true “king of certificates”—the Jiwei Ring-11 Tuning Fork Level Switch. This product has won the trust of global leading enterprises through its outstanding performance and reliability, and its comprehensive and authoritative certification system has redefined the industry standard for level measurement instruments in China.

1. The Value of Certification: More Than Just Paper, a Reflection of Capability and Responsibility

A certificate is far more than a piece of paper; it represents:

• Technical validation: Each certification indicates the product has passed rigorous design review, testing, and verification, meeting specific technical standards.
• Quality assurance: Certification bodies audit production processes and quality management systems to ensure consistency and reliability across batches.
• Market access: Some regions or industries require certified products to legally enter the market; a certificate acts as a “green card.”
• Foundation for functional safety: In high-risk industries, such as SIL-certified systems, a certificate can be the last line of defense to prevent accidents.

Ignoring the value of certificates or trusting fake ones is like planting a time bomb on a production line.

2. The “Certificate Crown” of Ring-11: A Comprehensive Certification System

The Jiwei Ring-11 Tuning Fork Level Switch is regarded as the “king of certificates” because it holds the most comprehensive and authoritative set of domestic and international certifications among Chinese level measurement products. This system covers functional safety, electrical safety, explosion protection, environmental compliance, electromagnetic compatibility, and global market access. Every certificate undergoes strict review and testing.

Let’s highlight the key certifications of the Ring-11 “crown jewels”:

• SIL2/3 (Functional Safety Certification): The Strictest Safety Guardian
  Core value: SIL (Safety Integrity Level) is the internationally recognized standard for measuring the reliability of safety-related systems and products. SIL2/3 certification indicates that Ring-11 has an extremely low probability of unsafe failure while performing its safety functions, meeting or exceeding the highest safety levels of many global leaders.
  Authenticity: Unlike the market’s “certificate-for-thousands” scams, Jiwei’s SIL certification is validated by an internationally authoritative third-party organization (Beijing Institute of Instrumentation, China) through rigorous hardware and software evaluation and FMEDA (Failure Modes, Effects, and Diagnostic Analysis). Its certificate can be publicly verified on the CNCA website, ensuring indisputable credibility. This is not a fake “Italian phishing site” result but an official national record. It is the Ring-11’s most brilliant and valuable certificate in the industry.
• PCEC (China National Explosion Protection Certification): The Pass for Hazardous Environments
  Core value: Explosion protection certification is a lifeline for products used in flammable and explosive locations. PCEC is China’s most authoritative national-level explosion protection body, with stringent standards covering multiple types of protection.
  Ring-11 advantage: Ring-11 holds full PCEC certification, ensuring safe operation in dust, gas, and other explosive environments, providing strong protection for chemical plants, oil depots, and pharmaceutical facilities.
• CE (Conformité Européenne, EU Mandatory Certification): Global Market Passport
  Core value: The CE mark allows products to enter the European market and indicates compliance with EU directives on health, safety, environmental protection, and consumer rights.
  Ring-11 advantage: CE certification confirms Ring-11 meets international standards, allowing smooth market access in Europe and other CE-recognized regions.
• EAC (Eurasian Conformity): Access to Belt and Road Markets
  Core value: EAC certification is mandatory for entering the Eurasian Economic Union (Russia, Belarus, Kazakhstan, Kyrgyzstan, Armenia) and sets strict requirements for product quality and safety.
  Ring-11 advantage: With EAC certification, Ring-11 can provide reliable level measurement solutions to Belt and Road countries, expanding its international reach.
• RoHS & REACH (Environmental Certification): Commitment to Green Manufacturing
  Core value: RoHS and REACH are EU directives regulating hazardous substances and chemicals, protecting human health and the environment.
  Ring-11 advantage: Compliance shows that Jiwei strictly controls hazardous substances in production, setting a benchmark for green manufacturing.
• CCC (China Compulsory Certification): Domestic Compliance Guarantee
  Core value: CCC ensures consumer safety, national security, and product quality management.
  Ring-11 advantage: Guarantees legal sales and use in China, meeting national safety and quality regulations.
• Other certifications (EMC, metrology, etc.): Ring-11 also passes strict electromagnetic compatibility tests and has national metrology approval, ensuring stable operation and measurement accuracy.

3. The True Value Behind the “King of Certificates”: Manufacturer Strength and Responsibility

The Ring-11’s accumulation of multiple authoritative certificates is no accident. It reflects Jiwei Automation’s long-term dedication to technology innovation, quality control, and functional safety as a vertically integrated level measurement manufacturer in China.

• Core technology expertise: Jiwei independently develops and produces everything from sensors to finished products, allowing strict control over quality and functional safety at every stage. This vertical integration is rare in China’s level measurement industry.
• Customer safety as a priority: In high-risk industries, even minor instrument failures can cause irreparable losses. Jiwei treats functional safety as a lifeline, investing heavily in high-level certifications like SIL to ensure customers receive truly reliable and safe products.
• Breaking import monopolies: With Ring-11’s performance and “king of certificates” status, Jiwei has successfully replaced traditional imported brands like VEGA’s VEGASWING 61 for demanding international clients such as Tesla, proving China’s capability in high-precision, high-safety instruments.

4. Conclusion: For Safety and Peace of Mind, Only a Reliable Manufacturer Can Deliver

In the world of industrial level measurement, especially in functional safety, “If you want safety and peace of mind, only a true manufacturer can provide it.” This is not just a marketing slogan—it is a truth proven by Jiwei’s Ring-11 “certificate crown.”

Choosing the Jiwei Ring-11 means more than purchasing a tuning fork level switch. It means selecting a product validated by multiple global authoritative institutions, ensuring safety, quality, environmental compliance, and international legitimacy. Ring-11 represents the highest level of Chinese high-end level measurement manufacturing and is a “king of certificates” trusted by users worldwide.
