the Application of Pressure Sensor
Pressure sensors are the most commonly used sensors in industrial practice.They are widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent building, production control, aerospace, military, petrochemical, Pressure Sensor oil, electricity, , Pipelines and many other industries, the following brief introduction to some commonly used sensor principle and its application.
The pressure sensor is the most widely used sensor.The traditional pressure sensor to the mechanical structure of the device-based, flexible components to indicate the pressure deformation, but this structure is large, heavy quality, can not provide electrical output. With the development of semiconductor technology, semiconductor pressure sensor also came into being. It is characterized by small size,light weight, high accuracy, good temperature characteristics.
Diffused silicon pressure transmitter is the isolation of silicon piezoresistive pressure-sensitive components packaged in a stainless steel shell made of. It can feel the liquid or gas pressure into the standard electrical signal output, QP series of diffused silicon pressure transmitter is widely used in the supply / drainage,heat, petroleum, chemical, metallurgical and other industrial processes on-site measurement and control.
Air compressors are essential equipment for a variety of factories,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,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, 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, the equipment and power grid will cause a greater impact.
Smart sensors are equipped with dedicated computers, and its rapid development will improve the safety performance of air compressors to an unprecedented height. 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.
