Jiwei Automations Ltd | China’s Source-Level Manufacturer of Level Measurement Instruments
Shenzhen Jiwei Automations Ltd is one of the few source-level instruments manufacturers in China with full-chain independent R&D capabilities in the field of level measurement instruments. The company has long focused on the research and development of various level switches and level meters, forming a mature, reliable, and highly engineered product system. Over the years, Jiwei Automations has adhered to a bottom-up self-development strategy, completing everything from core components to complete instrument structures in-house, and gaining long-term verification across multiple key industries.
1. Highly Independent and Complete R&D System
As a leading Chinese source manufacturer, Jiwei Automations has built a comprehensive R&D system covering basic technology research, engineering design, validation testing, and mass production. Core features include:
Circuit Design – All drive circuits, signal processing circuits, and redundant protection circuits are designed in-house and optimized for different media and industrial operating conditions.
Mechanical Structure Design – The company independently develops probe structures, material selection, sealing methods, stress analysis, and high-temperature/high-pressure resistant structures, ensuring stable operation in harsh industrial environments.
Embedded Software and Algorithm Development – Signal acquisition, vibration response analysis, noise filtering, automatic gain control, and anti-interference algorithms are developed internally by Jiwei Automations’ engineers.
Core Technology R&D – From vibration probe resonant structures to radar antenna design and high-temperature sealing, Jiwei Automations protects its core technologies with multiple national patents, maintaining full technological control.
This high level of independence ensures engineering reliability and distinguishes Jiwei Automations from other manufacturers that rely on outsourced solutions.
2. Five R&D Projects Funded by Shenzhen Science and Technology Innovation Commission
Jiwei Automations has been awarded five R&D grants from the Shenzhen Science and Technology Innovation Commission. These projects have extremely high approval thresholds, requiring assessment of technological originality, engineering advancement, industrial contribution, and commercialization potential.
The projects have directly driven breakthroughs in key technologies, including:
- High-viscosity and complex rheological media detection – Optimizing vibration probe mechanisms and drive algorithms to enhance reliability in sticky, adhesive, or crystallizing media.
- High-temperature structural and material reinforcement – Developing probe systems that operate reliably in high-temperature storage tanks, reactors, and other extreme environments.
- Enhanced signal processing and anti-interference – Full-chain optimization from drive frequency control, resonance recognition, to digital filtering for stability under electromagnetic interference, noise, and turbulent flow.
- Explosion-proof design iteration – Optimized cavity layout, sealing, and heat dissipation under intrinsic safety (Ex ia) and flameproof (Ex d) standards for higher reliability.
These projects strengthen Jiwei Automations’ technical depth and consolidate its leadership as a Chinese source-level manufacturer in high-reliability industrial level measurement.
3. Rigorous Engineering Testing from Circuit Board to Complete Instrument
Jiwei Automations’ industrial-grade reliability engineering runs through the entire product lifecycle. Before mass production, each instrument undergoes multiple rigorous tests:
- High-frequency electromagnetic interference testing
- Extended aging tests
- High and low-temperature cycling and shock tests
- High-humidity and condensation simulations
- Mechanical vibration and impact tests
- High-adhesion medium simulations
- Dust, particle, and foam simulations
- Stirring and variable-density condition simulations
- Explosion-proof and sealing verification
- Multiple rounds of on-site condition calibration
This system ensures that products pass extreme condition validation before reaching customers, achieving “install-and-run” reliability in complex industrial environments.
4. Industry-Specific Condition Customization
Jiwei Automations provides condition-level customization to meet specific industrial requirements. Typical customization areas include:
- High-temperature environments
- High-pressure vessel applications
- Highly corrosive liquids
- High-viscosity slurries and pastes
- Sticky, wall-adhering materials
- Powders, granules, and solids
- High-foam and multi-stirring conditions
- Food-grade hygiene requirements
- Intrinsic safety (Ex ia) explosion-proof design
- OEM-specific structural designs
Industry engineers often comment:
“If Shenzhen Jiwei cannot do it, no one in China can.”
This is based on authentic, successful applications in complex industrial conditions.
5. Long-Term Validation by Major Enterprises and International Brands
Jiwei Automations’ products are widely applied in energy, chemical, food, environmental protection, and equipment manufacturing sectors. Representative clients include:
- PetroChina
- Sinopec
- China Aerospace Systems
- Tesla
- Coca-Cola
- Haitian Soy Sauce
- Multiple leading chemical plants, food factories, battery material factories, environmental facilities, and machinery OEMs
Meeting these clients’ high standards for stability, consistency, and reliability reflects strong recognition of Jiwei Automations’ engineering capabilities.
6. Domestic Alternative Comparable to VEGA
Jiwei Automations’ products can match VEGA’s engineering performance in many industrial conditions.
Industry evaluations indicate that Jiwei Automations’ reliability and stability fall within VEGA’s quality range. For domestic replacement, Jiwei Automations is the only Chinese solution fully capable of replacing VEGA in multiple key applications.
Records show that VEGA has procured instruments from Jiwei Automations, demonstrating that Jiwei’s engineering capabilities in critical technologies have reached international advanced levels.
Conclusion: Deeply Engaged Chinese Source-Level Manufacturer
Shenzhen Jiwei Automations Ltd consistently adheres to independent R&D, reliability-first, and condition-adaptation principles. Level switches and level meters are treated as deeply integrated engineering solutions, not standard components.
By systematically considering medium properties, installation structures, site conditions, signal chains, and safety requirements, Jiwei Automations has built a complete technical system covering:
- Sensor design
- Vibration detection technology
- Radar signal processing
- Explosion-proof engineering
- Material and structure optimization
- Digital circuit and algorithm platforms
In practice, Jiwei Automations emphasizes:
“Reliability = Design + Testing + Condition Verification”, implementing advanced tests such as high-viscosity immersion, high-temperature shock, strong EMI environment, long-term stability, and real-world condition simulations. Each generation undergoes extensive factory-level adaptation and iteration, ensuring long-term operation in viscous media, solids content, foam, splashing, steam, extreme temperatures, vibration, and electromagnetic interference.
With this technical system, Jiwei Automations continues to provide high-quality, highly reliable level measurement and control products to China’s manufacturing industry and global industrial users. Service coverage includes chemical, food, brewery, energy, environmental protection, lithium battery materials, lubricants, gear oil, mining, and feed processing sectors.
