Explore pressure sensors: principles, applications, types and detection methods

With the intelligent development of electronics, pressure is everywhere, so the importance of sensors is becoming increasingly prominent. Naturally, it has become one of the most commonly used sensors in industrial practice and is widely used in a variety of environments, so let’s talk about pressure sensors today.

First, the principle of pressure sensor
The pressure sensor is a sensor that can feel the pressure and convert it into an available output signal. The pressure sensor is usually composed of a pressure sensing element and a signal conditioning circuit. By measuring and processing the output voltage of the bridge, the magnitude and variation of the pressure can be obtained.
Second, the application of pressure sensors
Pressure sensors are widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil Wells, electric power, ships, machine tools, pipelines and many other industries.
Three, there are several types of pressure sensors
A pressure sensor is a sensor that can sense pressure and convert it into an electrical signal, which can be used to measure the pressure of gases, liquids, and solids. There are many types of pressure sensors, common types include strain gauge pressure sensors, piezoelectric pressure sensors, capacitive pressure sensors, piezoresistive pressure sensors, resonant pressure sensors, etc.
Fourth, the role of pressure sensors
The functions of pressure sensors include: monitoring pressure, controlling pressure, protecting equipment, monitoring safety, etc. Pressure sensors play an important role in industrial, medical, environmental monitoring and other fields, and are an indispensable part of modern industry and scientific and technological development.
