Serve industrial automation instrumentation, strive to lead the sensing and control industry
With an in-house R&D team and production base, we specialize in customizing industrial automation instruments (e.g., pressure/level transmitters).
Under ODM mode, we provide full-process technical support from concept design to finished product delivery;
Under OEM mode, we strictly adhere to clients’ technical standards and quality requirements, supporting small-batch trial production and mass production.
We guarantee product consistency and stability, helping clients quickly launch customized products.

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.
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.
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.
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.

Primary packaging of high-precision single-crystal silicon pressure sensors is completed in a Class 100,000 cleanroom, equipped with specialized equipment including wire bonders, die bonders, high-precision high-temperature test chambers, and nitrogen cabinets for ultra-stable chip storage—guaranteeing cleanliness and precision in core component packaging.
End-to-end self-R&D & manufacturing: From chip packaging to sensor performance testing, we create a full-process technical closed loop, delivering tailored one-stop solutions for industrial on-site applications.

Core Philosophy:
Adhering to the core principle of "win-win with partners", Friende creates irreplaceable value for end-users through in-depth collaboration with ODM/OEM customers and system integrators.
