Product Description
The 300Bar ceramic concave diaphragm pressure module is a technologically sophisticated pressure sensing device. It uses high-quality ceramic as the substrate and uses a unique concave diaphragm structure created through fine craftsmanship to accurately sense and measure pressures up to 300Bar. It has excellent corrosion and wear resistance and can work stably in both the corrosive environment in the chemical industry and the high-intensity pressure shock in mechanical manufacturing. Its internal sensor element is highly sensitive and can quickly convert pressure changes into precise electrical signals, providing reliable pressure data support for many industries such as industrial automation control and automotive performance monitoring, effectively ensuring the safe and stable operation of the system and helping to optimize overall performance.

Product Display

- The ceramic concave diaphragm pressure module has excellent corrosion resistance. The ceramic material has stable chemical properties and can withstand corrosion from highly corrosive media such as acids and alkalis. It can also be used for a long time in harsh chemical environments.
- The ceramic concave diaphragm pressure module has excellent wear resistance. The special ceramic structure makes it hard and smooth. It can still maintain good condition in the face of frequent friction and impact, reducing loss.

- The ceramic concave diaphragm pressure module is highly sensitive and can keenly sense tiny pressure changes. Even extremely slight pressure fluctuations can be quickly captured and converted into accurate signal output, providing strong support for precision measurement and precise control.
- The module has high-precision characteristics. Through advanced manufacturing technology and strict quality control, its pressure measurement error is controlled within a very small range. Whether in data collection in scientific research experiments or in key parameter monitoring in industrial production, it can ensure high accuracy of the results.

- The ceramic concave diaphragm pressure module exhibits high stability. Whether it is under large changes in environmental factors such as temperature and humidity, or under the pressure of long-term continuous work, it can still operate stably, maintain the consistency and reliability of measurement performance, and reduce the error and failure risks caused by equipment instability.
- Its small size and easy packaging are also very prominent. The compact structural design makes it easy to adapt to various miniaturized and integrated equipment and systems, and realize efficient pressure measurement function in a limited space.
