What Are High-Temperature Pressure Sensors?

In many industrial fields, pressure measurement in high temperature environment is an important demand. For example, in high temperature kilns such as steel, ceramics, and glass, the pressure in the furnace needs to be accurately measured and controlled. This requires the sensor to withstand extremely high temperatures, while ordinary pressure sensors are easily damaged in high temperature environments and cannot meet this demand. Therefore, high temperature resistant pressure sensors have become the key to solving this problem.

High temperature resistant pressure sensor is a special sensor that can work normally in high temperature environment without being affected by heat. This sensor uses special materials and designs to maintain stability and accuracy at extremely high temperatures. At present, the maximum operating temperature of high temperature resistant pressure sensors has reached 1000 degrees.

Working principle of high temperature pressure sensor

The working principle of high temperature resistant pressure sensor is to use the deformation of elastic elements when subjected to pressure, and calculate the pressure by measuring this deformation. In high temperature environment, the elastic element and measurement circuit of the sensor will be affected by heat, resulting in a decrease in the performance of the sensor. Therefore, high temperature resistant pressure sensors need to pay special attention to how to reduce the influence of heat during design and manufacturing to ensure the accuracy and stability of the sensor in high temperature environment.

To achieve this goal, high temperature resistant pressure sensors use a variety of technical means.

First, the elastic element of the sensor is made of a special alloy material

This material has extremely high heat resistance and stability, and can maintain its original performance in a high temperature environment.

Second, the sensor’s measurement circuit uses advanced electronic technology and miniaturization technology

This allows the circuit to work normally in a high temperature environment and reduces the impact of heat.

Finally, the sensor uses a special heat dissipation system and protection measures

This can further reduce the impact of heat and protect the sensor from the influence of the external environment.

Applications of High-Temperature Pressure Sensors

High-temperature pressure sensors are widely used. In addition to the pressure measurement and control required in high-temperature kilns such as steel, ceramics, and glass mentioned above, they can also be used for pressure monitoring of high-temperature fluid pipelines and reactors in the fields of petroleum, chemical industry, and pharmaceuticals. In these fields, pressure monitoring and control in high-temperature environments are important factors to ensure production safety and stability. Therefore, the emergence of high-temperature pressure sensors provides a more reliable solution for these fields.

In addition to the above-mentioned application fields, high-temperature pressure sensors can also be used in other fields that need to withstand high-temperature environments. For example, in the aerospace field, rocket engines and aircraft engines need to work at extremely high temperatures, and ordinary pressure sensors cannot withstand such high temperature environments. Therefore, high temperature resistant pressure sensors can be used in these fields to provide accurate and reliable pressure monitoring data for the engine.

Conclusion

In short, high temperature resistant pressure sensors are very useful sensors that can work normally at extremely high temperatures and have high stability and accuracy. Its emergence provides more reliable solutions for many fields and provides important guarantees for production safety and stability. With the continuous development of science and technology, it is believed that the performance and application scope of high temperature resistant pressure sensors will be further improved and expanded.
