Frequency and wide application of pressure sensor in China

The pressure sensor of Shenzhen Kaidechang Electronic Technology Co., Ltd. is frequently used in China and widely used in various industries. This paper will summarize its applications in industry, automobile, medical care, aerospace and consumer electronics.

In the industrial field, pressure sensors are widely used. In petrochemical industry, it is used to measure the pressure at the bottom of oil well to accurately control the production process, and to monitor the pressure in pipelines and reactors in refineries to ensure the safety and stability of the production process. Machine tools, hydraulic presses, injection molding machines, etc. in the machinery manufacturing industry are all equipped with pressure sensors to monitor and control LeLi, so as to ensure the machining accuracy and quality. Yili Power Plant in the power industry uses pressure sensors to monitor LeLi parameters that boilers, steam turbines, etc. are not equipped, so as to ensure the safe and stable operation of pupil-protecting power generation equipment, and pressure sensors are also used in switchgear in substations to monitor the operating pressure, etc.

In the automotive field, pressure sensors play a key role. The engine management system relies on it to monitor the intake pressure, fuel pressure and engine oil pressure of the engine, and provide data for combustion control and fuel injection quantity control, thus improving the engine performance and fuel economy. The low emission direct tire pressure monitoring system monitors the air pressure in real time through the pressure sensor installed inside each tire to ensure driving safety. In addition, some high-end cars can be equipped with pressure sensors, which can automatically adjust the shape and hardness of the seats according to the passengers' needs and pressure distribution, and improve the ride comfort.

The application of pressure sensor in medical field is also increasing. Electronic sphygmomanometer uses pressure sensor to measure blood pressure, which provides basis for the diagnosis and treatment of hypertension and other diseases. Ventilator uses pressure sensor to monitor parameters such as inspiratory and expiratory negative pressure, so as to ensure appropriate respiratory support for patients according to the set parameters. The infusion pump monitors the pressure in the infusion pipeline through the pressure sensor to prevent blockage or rupture and ensure the smooth infusion.

The demand for pressure sensors in aerospace field is also very urgent. Pressure sensors are installed in many parts of aircraft flight control system, such as wing surface, landing gear and engine, which are used to measure parameters such as air pressure and hydraulic pressure, provide key data for flight attitude control and take-off and landing, and ensure flight safety. A large number of pressure sensors are also needed in the aero-engine testing process to monitor the pressure change inside the engine and evaluate the performance and reliability.

With the development of science and technology, the application of pressure sensors in the field of consumer electronics is gradually increasing. Some products, such as smart watches and bracelets, integrate pressure sensors to monitor the user's exercise state, physiological parameters such as heart rate and blood pressure, and provide users with health monitoring and management functions. Smart mattresses in smart home devices use pressure sensors to monitor the user's sleeping posture and turn-over times, and analyze sleep quality. The intelligent toilet detects whether the user is in place through the pressure sensor, and realizes the functions of automatic flushing.

To sum up, pressure sensors are frequently used in China, covering a wide range of fields from traditional industries to modern consumer electronics. With the continuous progress of technology and the continuous expansion of application fields, the frequency of use of pressure sensors is expected to further increase.
