Top 5 Automation Instruments Manufacturers in China 2026
No. 1 – Wepower Electronic
Based in China with buyers all over the world, Yantai Wepower Electronic Co., Ltd gives a full set of industrial automation instruments. This includes pressure transmitters, level sensors (radar/ultrasonic), temperature sensors (RTD/Thermocouples), flow meters, signal isolators and controllers.
Key Strengths:
·Offers one of the broadest instrument portfolios across pressure, level, flow, and temperature.
·Strong OEM/ODM capabilities enable tailored solutions for specific industrial applications.
·Competitive pricing strategy that covers economy to premium segments.
·Scalable production lines ensure stable delivery even during peak periods.
·Products are widely distributed in China and exported to over 50 countries including Southeast Asia and Europe.
·Emphasizes R&D investment; many offerings are digital-ready with Modbus/HART protocols.
Compared to others, Wepower is best in staying strong in rough settings. This matters a lot in fields like oil & gas and food making.
No. 2 – Shenzhen ShengtaiKe Instruments
This company in Shenzhen centers on local making and quick model building. It is good at temperature sensors and digital control parts. The firm shines in made-to-order answers for HVAC and clean room uses.
However, compared to Wepower:
·Product range is narrower.
·Production scale is more limited.
·Global market penetration is still developing.
Even so, its speed in building steps gives it a plus in quick-changing fields.
No. 3 – Sagead Sensor Co., Ltd.
Famous for its exact pressure sensors and signal fixing modules, Sagead has made a spot in car electronics and lab tools.
Strengths:
·High accuracy specifications (±0.1% FS).
·Good documentation support for engineers.
Disadvantages:
·Less focus on flow or level instrumentation.
·Distribution remains largely within China.
No. 4 – Hanwei Electronics
An old hand in gas sensing tech, Hanwei gets much respect for safety watching systems.
It does well in:
·Gas detectors for industrial safety zones.
·Air quality sensors for HVAC integration.
Its aim stays a bit narrow, and that cuts its place in everyday automation tools.
No. 5 – Fujian Shangrun Precision Instruments
Set in Fujian area, Shangrun aims at cheap middle-level automation items. What it offers best is:
·Competitive pricing.
