As a professional diffused silicon pressure sensor manufacturer, Xi'an Shenghongchuang takes you deep into the HUBA522 pressure transmitter production workshop, revealing the 5 core quality control processes from raw material screening to finished product testing. This article is specifically aimed at corporate procurement decision-makers, analyzing the localized implementation of German process standards to help you accurately evaluate the technical strength and quality control level of huba pressure transmitter manufacturers.

I. Raw Material Screening: The Perfect Combination of German Standards and the Local Supply Chain

On the production line of the HUBA522 pressure transmitter, raw material screening is the first checkpoint of quality control. Xi'an Shenghongchuang uses diffused silicon chips of the same grade as the original German HUBA factory, with temperature stability reaching ±0.01%FS/℃. We have established a strict supplier audit system, and all metal housings must pass salt spray testing (ASTM B117 standard), while sealing materials must meet the oil resistance requirements of ISO 3601-3. It is particularly worth noting that, in view of the characteristics of the domestic industrial environment, we have optimized the overload resistance of the sensor diaphragm, making it especially outstanding in high-pressure models such as 40-1005.

II. Precision Welding Process: Ensuring Long-Term Stability

The welding quality of the core components of the pressure transmitter directly affects the product service life. Our production workshop is equipped with imported German laser welding equipment, and the weld strength reaches more than 95% of the base material. Through real-time monitoring of the welding temperature curve with an infrared thermal imager, we ensure that every weld point of each HUBA506 series product complies with the EN 14620 standard. This process enables the sensor to maintain micron-level detection accuracy when measuring mechanical quantities such as tension and pressure, forming a perfect complement to the high-precision characteristics of the domestic displacement sensor SDVE28-15A differential pull-rod linear displacement sensor spring-return inductive sensor.

III. Temperature Compensation Calibration: Overcoming Industrial On-Site Challenges

To address the temperature drift issue that enterprise users care about most, we have established a full-temperature-range compensation system from -20℃~120℃. Each HUBA522 pressure transmitter must undergo 3 rounds of temperature cycle testing, and a polynomial compensation algorithm is used to control the temperature error within 0.5%. This technical indicator has surpassed similar domestic products and is even better than some imported brands. Our engineering team has developed intelligent calibration software that can automatically record the temperature characteristic curve of each sensor, ensuring that models such as PY-PY210 still maintain stable output in extreme environments.

IV. Full-Process Sealing Test: Eliminating Leakage Risks

Sealing performance is the lifeline of liquid and gas pressure sensors. Xi'an Shenghongchuang uses a helium mass spectrometer leak detector (with sensitivity up to 5×10⁻⁸Pa·m³/s) for 100% full inspection, and all AKS-AKS3000 series products must pass IP68 protection rating certification. Our original "three-stage pressurization test method": first conducts a 1.5 times rated pressure test, then undergoes 1000 pressure cycles, and finally carries out a burst pressure test. This rigorous testing process has made our products highly praised in high-risk fields such as chemicals and oil & gas.

V. Comprehensive Pre-Delivery Testing: Assurance of Data Traceability

Before packaging and shipment, each MBS-MBS1200 pressure transmitter must complete a final inspection including 12 indicators:

• 24-hour zero-point stability test (error ≤0.1%FS)
• Step pressure response test (rise time <1ms)
• EMC anti-interference test (compliant with EN 61326 standard)
• Vibration test (10-2000Hz sweep frequency test)

All test data are automatically entered into the MES system, generating a unique QR code traceability file. This transparent quality management model is exactly the key to establishing the reputation of the Huba691 pressure transmitter in industries such as electric power and metallurgy.
