Application|temperature & pressure sensor in powder metallurgy industry

Powder metallurgy is a method of producing dense materials by pressing and sintering metal or alloy powders. This method not only significantly saves materials but also allows for the manufacture of complex-shaped, high-performance parts, widely used in automotive, aerospace, electronics, tool manufacturing, and other fields.

In the powder metallurgy process, the sintering step is a crucial stage, directly affecting the physical properties and structural quality of the final product.

Sintering is the process of heating the pressed powder compacts at high temperatures to form metallurgical bonds between the powder particles. During the sintering process, temperature and pressure are key parameters that affect the sintering results. Therefore, precise and stable temperature and pressure control are particularly important. In addition, the cooling process is also a critical step in sintering, where the compacts must be cooled slowly in a controlled environment to prevent thermal stress and deformation, ensuring the quality and performance of the final product.

Importance of Sensors in the Sintering Process

Due to the high requirements for precise control of temperature and pressure in the sintering process, sensors play an irreplaceable role. Temperature sensors need to monitor the temperature inside the sintering furnace in real-time to ensure that the sintering temperature at different stages is within the optimal range. Pressure sensors, on the other hand, need to accurately monitor the pressure inside the sintering furnace to prevent the oxidation of the powder particles. The accuracy and stability of this data directly determine the success of the sintering process.

Our Products

SE Series Pressure Sensors

The SE Series (piezoresistive) pressure sensors are designed to withstand harsh industrial environments, with a robust stainless steel casing ensuring long-term durability and reliability. The unique design allows the body to rotate up to 330 degrees, making the installation process easier. Additionally, our sensors are equipped with a 4-digit 7-segment digital display that supports mirror flip function, making data reading more convenient and intuitive. Three programming buttons provide simple and intuitive operation, making parameter configuration easier.

TB Series Temperature Sensors

The TB Series PT100 temperature sensors, as a new type of temperature monitoring device, focus on practicality and accuracy, aiming to provide reliable temperature monitoring solutions for various industrial applications. Users can customize the analog temperature range and probe length according to their specific needs, ensuring that the sensors can perfectly adapt to various specific application scenarios.

Application Cases

A domestic sintering furnace manufacturer uses our company's SE Series pressure sensors and TB Series temperature sensors in their equipment. The two sensors perform their respective duties, with the pressure sensor monitoring the pressure inside the sintering furnace and the temperature sensor monitoring the temperature of the cooling system, ensuring the stable operation of the equipment.

The high-quality product reduces equipment failure rates; stable delivery times improve production efficiency, bringing greater benefits to customers.

Comprehensive Upgrade

In 2024, we have comprehensively upgraded our original temperature and pressure sensor products to further enhance their performance and applicability. The upgraded sensors have improved appearance, with an integrated injection-molded operation panel that provides a higher protection level, capable of withstanding high-pressure water jet washing, ensuring stable operation in various harsh industrial environments.

In addition, our new generation of sensors integrates IO-Link functionality, endowing the sensors with intelligent features. This function not only supports digital communication and remote diagnostics but also provides more output options to meet the diverse needs of different customers. With these upgrades, our sensors offer higher precision, better stability, and stronger adaptability. Their quality and functionality are comparable to imported brands, providing better support for customers' "intelligent manufacturing".
