Pressure sensors are one of the more common sensors. Conventional pressure sensors are primarily mechanical devices, and the deformation of elastic parts indicates pressure. However, due to their size and weight, they are unable to generate electricity. The development of semiconductor skills has also led to the emergence of semiconductor pressure sensors. It is characterized by small size, light weight, high precision and good temperature performance. In particular, with the development of MEMS skills, semiconductor sensors are moving towards miniaturization, low power consumption, and high reliability.
What is the function of a pressure sensor?
Pressure sensors are widely used in hydropower, railways, intelligent buildings, production management, aerospace, petrochemical, oil wells, power, ships, machine tools, pipelines and other occupations. The following is an overview of common sensor principles and applications. There is also a medical pressure sensor.
What is the function:
1. Directly used to measure different pressures: air pressure, hydraulics, hydraulics (including hydraulics), different blood pressures in daily life, etc.;
2. Pressure sensors are used in sedans, some elite motorcycles and almost all internal combustion engines;
3. Liquid level: The field equipment used for various liquid level measurement is the pressure sensor, first of all;
4. Most of the electronic weighing signals and vehicle weighing signals come from pressure sensors.
Pressure sensors are also used to measure acceleration in the aerospace industry.
Classification of uses:
1. Component system
Pressure sensing skills are increasingly being used in commercial weighing systems in industrial handling skills. In a wider range of pressure manipulation processes, it is generally necessary to collect pressure signals and convert them into electrical signals for automatic control. The pressure regulator of the pressure sensor is generally referred to as an electronic weighing system. As a networked thing, electronic weighing systems are becoming increasingly important in monitoring material activity in a variety of industrial processes. The electronic weighing system not only optimizes production and improves product quality during production, but also stores the data flow during production and transmits it to the data center for inventory management and accounting.
2. Petrochemical industry
The pressure sensor is one of the commonly used measuring instruments for control automation in the petrochemical industry. Almost all pressure sensors are used in large-scale chemical projects: differential pressure, absolute pressure, gauge pressure, high pressure, micro differential pressure, high and low temperature remote flange pressure sensors for a wide range of materials and special processing. The demand for pressure sensors in the petrochemical industry is mainly concentrated in three aspects: reliability, stability and high accuracy. This encompasses reliability and many additional requirements such as ratio, tire type, etc. The stability and high accuracy of the pressure sensor are first ensured by the stability and measurement accuracy of the pressure sensor.
3. Environmental maintenance
In recent years, China's ecological water treatment profession has developed rapidly and has broad prospects. The use of pressure sensors in water distribution and wastewater treatment provides companies with important things to manipulate and manipulate to maintain and ensure quality.
4. Pharmaceutical occupations
With the development of medical device stores, the medical profession has put forward more stringent requirements for the accuracy, reliability, stability and operability of pressure sensors. Pressure sensors are more suitable for minimally invasive catheter ablation and temperature sensor measurement.
Today, pressure sensors are primarily used to manipulate and monitor certain applications. In the passenger car industry, MEMS pressure sensors are mainly used to measure fuel pressure, tire pressure, airbag pressure and pipeline pressure; In the biomedical field, MEMS pressure sensors are mainly used in diagnosis and detection systems; In the aerospace profession, MEMS pressure sensors are primarily used to control spacecraft and spacecraft orientation; In industrial applications, MEMS pressure sensors require three primary criteria: accuracy, power consumption, and reliability; In the field of repetitive consumption, MEMS sensors are used in consumer electronics, including motion and fall detection, navigation data compensation, gaming/human-machine interface, etc. The car profession is the most traditional and largest shopping mall for MEMS pressure sensors.
