There are many types of pressure sensors, and pressure sensors are among the most mature technologies. In terms of market conditions, they are the first among sensors, and have an annual growth rate of 20%, which has broad application prospects. The application of pressure sensors with different technical properties to different measurement needs has become an important part of the development and application of current pressure sensors.
Selection of pressure sensor
1. Due to the different structures, pressure sensors can be divided into absolute pressure, relative pressure to the atmosphere and differential pressure; the corresponding pressure sensor needs to be selected according to the application.
2. Choose the appropriate pressure level according to the pressure range.
3. Make the correct selection according to the accuracy requirements of the pressure sensor.
4. Choose according to the operation mode. For example, when the sensor is used for gas pressure measurement and liquid pressure measurement, the situation is different.
5. Choose according to temperature requirements.
Application of pressure sensor
Broadly speaking, all kinds of sensors composed of various physical effects of piezoresistive materials can be called pressure sensors.
Usually in this case, the pressure sensor will be used in hydraulic machines, hydraulic stations, fatigue machines, pneumatic and hydraulic systems, pressure tanks, hydraulic test stands, test instruments, energy and water treatment systems, etc.
In recent years, China's pressure sensor technology is booming and its application fields are rapidly expanding. Because pressure sensing technology involves a wide range of technologies and almost penetrates into various professional fields, therefore, the discussion of new theory of pressure sensors, the application of new technologies and methods, the research of new materials and new processes will become the development trend.
