Publish Time: 2024-05-29
In the process of designing and manufacturing ceramic pressure transmitters, in order to reduce errors and improve the consistency and reliability of products, the following measures can be taken:

1. Considerations in the design stage

Optimize structural design: Through reasonable structural design, reduce the impact of external factors such as temperature and vibration on sensor performance. For example, ensure that the two pressure pipes maintain the same temperature to reduce the error caused by the temperature difference.

Use new packaging technology: For example, the new solid-state packaging technology of sensors mentioned in reference article 5 fundamentally eliminates rubber and bakelite gaskets, and realizes solid-state packaging of thick film pressure chips, thereby improving sensor accuracy, stability and reliability.

Accurate material selection: When selecting materials, factors such as long-term stability and corrosion resistance of materials need to be considered, such as stainless steel, titanium alloy and other highly corrosion-resistant materials, to ensure that the product can work stably in harsh environments.

2. Control in the manufacturing stage

Strictly control the manufacturing process: During the processing and manufacturing process, the processing equipment is strictly controlled to ensure the reliability of manufacturing quality. At the same time, the manufacturing process needs to be carried out according to standard procedures to ensure that the products are consistent and comparable.

Use high-precision processing technology: such as CNC processing, welding, calibration and other processes, which require meticulous operation to ensure the accuracy and stability of the product.

Introducing high-temperature bonding technology: For example, the high-temperature bonding technology for chip external leads mentioned in reference article 5, adopts high-temperature pressure welding technology to achieve high-temperature bonding of chip external leads, and improves the operating temperature, reliability and stability of the sensor.

3. Testing and calibration

Strict quality inspection: In the last link of the manufacturing process, the pressure transmitter needs to be tested in multiple aspects, including appearance inspection, functional testing, calibration inspection, etc. Only after multiple layers of testing can we ensure that the pressure transmitter products that meet the requirements are manufactured.

Regular calibration: For products that have been produced, regular calibration is required to ensure their measurement accuracy and reliability.

4. Continuous improvement

Collect user feedback: By collecting user feedback during use, possible problems with the product are discovered and targeted improvements are made.

Technological innovation: Continuously introduce new technologies, materials and processes to improve product performance and quality.

In summary, by taking effective measures in multiple links such as design, manufacturing, testing and continuous improvement, the error of ceramic pressure transmitters can be significantly reduced, and the consistency and reliability of products can be improved.
