The core sensing element is the "heart" of a pressure transmitter. We firmly believe that only by mastering core technologies can we guarantee the ultimate performance of our products.
In-House R&D and Production: The core chip and key sensing element are entirely designed, developed, and manufactured in-house. From chip design and diaphragm packaging to oil filling and temperature compensation, the entire process is completed under a strict, self-controlled manufacturing system.
High Reliability and Consistency: By avoiding the drawbacks of outsourced sensing elements—such as inconsistent quality and external technical reliance—we ensure every transmitter leaving our factory delivers outstanding zero-point stability, superior overload resistance, and exceptional long-term thermal drift performance.
Superior products rely on state-of-the-art equipment. We have invested heavily in building industry-leading automated production lines and high-standard laboratories:
Full-Suite Production Equipment: We import top-tier international brands for laser welding, vacuum oil filling, and automated micro-adjustment equipment to ensure micron-level manufacturing precision.
Meticulous Quality Inspection System: Equipped with world-class temperature compensation chambers, pressure calibration standards, and Electromagnetic Compatibility (EMC) testing platforms, every product undergoes rigorous multi-cycle high-and-low temperature stress tests, full-scale aging, and overpressure shock testing to guarantee 100% compliance before shipment.
Relying on exceptional product performance, our pressure transmitters and submersible liquid level transmitters fully comply with and satisfy multiple international and national standard certifications:
IEC Standards: IEC 61298-1 (Process measurement and control devices - General methods and procedures for evaluating performance), IEC 61298-2 (Tests under reference conditions), IEC 60770 (Transmitters for use in industrial-process control systems)
Chinese National Standards: GB/T 42567.2-2023 (Reference conditions and procedures for testing industrial-process measurement transmitters - Specific procedures for pressure transmitters), GB/T 28474.1-2012 (Pressure/differential pressure transmitters for use in industrial-process measurement and control systems - General specification), GB/T 34073-2017 (Specification for IoT pressure transmitters), GB/T 11828.2-2022 (Instruments for stage measurement - Pressure level meter), JJG 882-2019 (Verification regulation of pressure transmitters)
US Standards: ANSI/ISA-12.27.01 (Requirements for Process Sealing Between Electrical Systems and Flammable or Combustible Process Fluids)
European Standards: EN 61298-2 (Process measurement and control devices - Tests under reference conditions), DIN EN 62828-2 (Test procedures for pressure transmitters)
From in-house core sensing elements to top-tier international quality inspection equipment, and from Chinese national standards to international specifications such as IEC and ANSI—we master full supply-chain autonomy and align with international standards across the entire process, delivering high-performance, highly reliable transmitters to earn the trust of the global market with solid expertise.
