What Is Jiangsu Suyi Group Co., Ltd. (Jiangsu Hongguang Instrument Factory)?

Jiangsu Suyi Group Co., Ltd. is a Chinese industrial instrumentation and automation manufacturer built around Jiangsu Hongguang Instrument Factory, which was founded in 1972. It makes process instruments (pressure, temperature, level, flow, display), calibration and standard instruments, cables, valve and instrument cabinet products, gas detection and analysis equipment, and synchronous reluctance motors. It is a credible candidate supplier for petrochemical, power, and steel projects — but you should verify the specific product, certification, and commercial terms for your application before ordering.

Company identity and history

• The group was formed with Jiangsu Hongguang Instrument Factory as its main body; the factory dates to 1972, giving it roughly five decades of instrument development and production experience.
• It describes itself as one of the instrument manufacturers formerly designated by the national machine-building ministry.
• It positions itself as a leading enterprise of the Huai'an Jinhu instrumentation characteristic industrial base, a National High-Tech Enterprise, and a National Specialized and Sophisticated "Little Giant" Enterprise.
• It is a council member of the Automation Branch of the China Instrument and Manufacturers Association.
• It operates provincial-level research platforms: an industrial automation thermal instrument engineering technology research center, an enterprise technology center, an industrial automation process control instrument engineering research center, a provincial graduate workstation, a provincial postdoctoral innovation practice base, and a provincial demonstration smart workshop.
• It reports more than 80 patented products with independent intellectual property rights and completion of multiple national and Jiangsu provincial science and technology projects.

What it manufactures

The product range is broad, which matters if you want to consolidate several instrument categories with one supplier:

Customers and industries served

The company states it is a supplier to Sinopec, PetroChina, the five major power groups, and enterprises accounting for about 70% of China's large steel producers. Its published case examples include:

• Energy-saving "flux-assisted" synchronous reluctance direct-drive motors in chemical applications
• The same motor line in pharmaceutical applications
• Two 660 MW ultra-supercritical units at Huadian Shiliquan Power Plant

This customer profile is a useful signal for heavy-process industries, but it is a self-reported list — ask for references or project documentation relevant to your own sector.

Certifications and qualifications

According to the company, it has passed:

• Quality, environmental, occupational health and safety, measurement, and industrialization-informatization integration management system certifications
• Product certifications including various explosion-proof certifications, SIL safety integrity level certification, and CE marking

For safety-related or hazardous-area applications, request the actual certificate numbers and scope, since certification applies per product and per configuration, not to the company as a whole.

How to evaluate it as a supplier

1. Match the product to your process conditions. The catalog spans commodity gauges to SIL-rated and explosion-proof instruments. Confirm the exact model, pressure/temperature rating, wetted materials, and output signal.
2. Check certifications against your requirement. If you need SIL, explosion-proof (e.g., Ex ia/Ex d), or CE, ask for the certificate covering the specific model you are buying.
3. Verify industry experience. Ask for case references in your sector and, where possible, contact those customers.
4. Confirm commercial terms directly. The website does not publish prices, lead times, minimum order quantities, or payment terms, so these must be obtained through an inquiry.
5. Use the official site for product and contact details. The site (jshgyb.com) organizes content under About Us, Product Series, Success Cases, News, Online Message, and Contact Us, with an English-language version available via the "ENGLISH" link — useful if you are sourcing from outside China.

Bottom line

Jiangsu Suyi Group is an established Chinese instrument manufacturer with a long operating history, a wide product portfolio, and stated credentials in high-tech and specialized-enterprise programs, plus a customer base in petrochemical, power, and steel. It is worth shortlisting for industrial instrumentation and automation procurement. Treat the website as a starting point: validate the specific product's certifications, request references, and confirm pricing and delivery terms before committing.
