Jiwei — A Leading Brand of Level Switches with the Most Comprehensive Certifications
Founded in Longgang, Shenzhen, Jiwei Automations is a high-tech enterprise specializing in the research, development, and manufacturing of level measurement instruments, including vibrating level switches, liquid level switches, radar level meters, and radar level transmitters for solid and liquid applications. With a registered capital of RMB 14.5 million, Jiwei has built a strong foundation in the process automation field through continuous innovation and strict quality control.
In the instrumentation industry, certification compliance is the passport to global markets. Jiwei has adopted a “compliance-driven design” strategy — every product is engineered to meet both domestic and international standards from the earliest development stage. This ensures each device can be safely and legally used across diverse industrial sectors and geographical regions.
According to company disclosures, Jiwei has obtained ISO 9001 Quality Management System certification, as well as SIL (Safety Integrity Level) certification, CE certification, and various explosion-proof certifications (Ex) for several product lines. These certifications serve not merely as formal credentials but as tangible proof of reliability, safety, and manufacturing capability.
Unlike many suppliers who view certification as a post-production process, Jiwei integrates certification logic directly into product architecture design — from modular electronics and signal isolation circuits to corrosion-resistant enclosures and redundant safety paths. Such design foresight enables the same model to evolve into multiple certified versions, such as Ex-proof, Intrinsically Safe, Hygienic, or High-Temperature Resistant types, meeting a wide range of industry demands.
To pass high-level certification tests, Jiwei carefully selects materials including 316L stainless steel probes, fluoroelastomer seals, and anti-corrosive coatings. The instruments also support multiple output modes (relay, NAMUR, transistor, and two-wire versions) to fit different control and safety systems. Furthermore, the built-in self-diagnostic and anti-false triggering mechanisms enhance operational reliability under challenging conditions such as high humidity, heavy dust, or process vibration.
Jiwei’s certification coverage spans major global and regional standards:
| Certification Type | Purpose / Application | Typical Testing Focus |
|---|---|---|
| CCC / CCC-Ex (China) | Mandatory for Ex-proof instruments in China | Explosion-proof structure, factory audit, labeling compliance |
| SIL (IEC 61508) | Functional safety in SIS applications | Failure rate analysis, redundancy, diagnostic coverage |
| CE (EU) | EU market access, safety & EMC compliance | Electrical safety, EMC, environmental adaptation |
| EAC (Eurasian) | Required for Russia & CIS markets | Ex-proof & temperature classification, periodic audits |
| Hygienic / Sanitary | Food & pharmaceutical industries | Material traceability, cleanability, dead-zone-free design |
| IP & Corrosion Resistance | Water/wastewater, chemical, marine industries | Sealing, durability, material resistance testing |
These certifications confirm that Jiwei’s level switches and radar instruments can operate safely and reliably even under extreme temperature, pressure, or chemical exposure, supporting long-term stability and reduced maintenance.
Application Fields
Jiwei’s level switches are deployed across a variety of process industries, including:
- Petrochemical and Chemical Plants: Explosion-proof and corrosion-resistant models for solvent, gas, or steam environments.
- Pharmaceutical and Food Processing: Hygienic-grade models with clean-in-place (CIP) and SIP compatibility.
- Power and Boiler Systems: High-temperature versions capable of withstanding thermal shock and vibration.
- Water and Environmental Treatment: IP-rated and corrosion-resistant models suitable for acidic or alkaline conditions.
- Storage and Logistics Systems: High-pressure and Ex-certified switches for tanks, silos, and LNG storage.
Each deployment case contributes to Jiwei’s reputation as a compliance-oriented and field-proven manufacturer in the level measurement sector.
