Pressure Sensor Development Of
Edit: Hanzhong Quanyuan Electronic Co.,Ltd    Date: Jul 21, 2017

Compared with the acceleration sensor, Pressure Sensor the pressure sensor in the detection of side impact speed, faster than the acceleration sensor nearly 3 times, and the probability of malfunction is smaller. It is worth mentioning that the miniaturization of the sensor using micro-machining technology will be micron-level sensitive components, signal conditioning, data processing device integrated package on a chip. Because of its small size, Pressure Sensor low cost, easy integration and other characteristics, can improve the system test accuracy, such as the micro-pressure sensor and micro-temperature sensor integrated together, while measuring the pressure and temperature, through the chip operation to eliminate the pressure measurement Temperature effect. There are many micro-sensors available, Pressure Sensor such as pressure sensors.

With the development of microelectronics technology and micro-machining technology, the sensor is moving in the direction of miniaturization, multi-function and intelligent. Industry experts are optimistic about the development of air compressor sensor in China's prospects. They believe that the increase in the number of air compressors and the increase in the number of sensors used on each air compressor, the decision of the Chinese sensor market capacity will continue to increase, the Chinese sensor market is entering a period of vigorous development.

Air compressors are essential equipment for a variety of factories, Pressure Sensor road construction, mining and construction industries and are mainly used to provide a steady stream of compressed air, such as air supply to pneumatic valves, to a process that requires a certain pressure gas Gas source. There are many types of air compressor, such as screw air compressor, piston air compressor, Pressure Sensor centrifugal air compressor, scroll air compressor, etc., while the screw air compressor market potential is great, and in many Industry has been widely used. Air compressor in its control using the loading - unloading valve to control the air compressor air supply, gas equipment due to the work cycle or the difference between the production process, Pressure Sensor making the gas fluctuations, and sometimes cause frequent loading air compressor, Unloading. Air compressor unloading is still running after the frequency, not only a waste of energy and increase the mechanical wear of equipment, and loading is a sudden process, Pressure Sensor the equipment and power grid will cause a greater impact. So the air compressor frequency conversion to improve the motor to start and run to reduce the mechanical wear and tear equipment, in a certain range to save energy and other effects.

Corrosion-resistant ceramic pressure sensor without the transmission of liquid, the pressure directly on the front surface of the ceramic diaphragm, the diaphragm has a small deformation, Pressure Sensor thick film resistance printed on the back of the ceramic diaphragm, connected into a Wheatstone bridge Bridge), due to the varistor piezoresistive effect, so that the bridge produces a linearity proportional to the pressure, proportional to the excitation voltage is the voltage signal, the standard signal according to the pressure range of different calibration for the 2.0 / 3.0 / 3.3 MV / V, etc., and strain sensor can be compatible. Through the laser calibration, Pressure Sensor the sensor has a high temperature stability and time stability, the sensor comes with temperature compensation 0 ~ 70 ℃, and can be in direct contact with the vast majority of media.

Ceramics is a recognized high elasticity, corrosion resistance, Pressure Sensor abrasion resistance, impact and vibration of the material. The thermal stability of the ceramic and its thick film resistance can make its operating temperature range up to -40 ~ 135 ℃, and has a high precision measurement, high stability. Electrical insulation degree> 2kV, the output signal is strong, long-term stability. High-performance, Pressure Sensor low-cost ceramic sensor will be the direction of development of pressure sensors in Europe and the United States have a comprehensive alternative to other types of sensor trends in China, Pressure Sensor more and more users to use ceramic sensors instead of diffusion silicon pressure sensor.
