Factory Information
Production Line

As a professional pressure transmitter manufacturer, we have a 2,500㎡ standardized production workshop, focusing on R&D and manufacturing of high-precision Monocrystalline silicon pressure transmitters. With imported core components, advanced equipment and full-process quality control, we provide stable and accurate measurement solutions for global industrial customers.

1.Core Technology: High-Precision Temperature Compensation

Adopting imported ultra-stable chips, combined with WIKA controllers, ESPEC temperature chambers and self-developed compensation systems, realizing fully automatic unattended temperature compensation. Conventional temperature range -20~60℃ (adapting to 85%+ industrial scenarios), extendable to -40~80℃; 1kPa~40MPa range accuracy traceable to 1/10,000, nitrogen pressurization ensures clean and pollution-free products.

2.Lean Production: Efficient Standardized Process

Lean production lines built under professional guidance, the second line under construction. Some products take only 180 seconds from assembly to packaging, efficiency increased by 40%, daily capacity about 220 units. Equipped with WIKA controllers and Keysight 6.5-digit multimeters, employees follow standardized operations to ensure production consistency.

3.Key Processes: Strict Quality Control

Flange Forming & Oil Filling: Forging process + Agilent helium leak detection, fillable with ordinary silicone oil, high-temperature silicone oil and other suitable media.

Automatic Screw Locking & Static Pressure Leakage Test: Automatic screw locking machine ensures torque and parallelism, differential pressure products undergo static pressure leak test before delivery.

Power-On Aging Test: 24-168 hours pressurized/non-pressurized aging, each product generates independent curve to record stability.
