What is a pressure sensor, the working principle, application, and development trend of pressure sensors 1

1、 Overview of pressure sensors

Pressure sensor 2N7002 refers to a type of sensor that can convert physical pressure into electronic signals. Due to the different working principles and application scenarios of pressure sensors, they are divided into many types, such as piezoelectric, capacitive, resistive, welded, microelectromechanical systems (MEMS), etc. In modern industry, pressure sensors are widely used in aerospace, automotive, machinery, chemical, power, medical, environmental monitoring and other fields.diode

2、 Working principle of pressure sensor

Regardless of the type of pressure sensor, their working principle is to convert pressure into electrical signals. Taking the resistive pressure sensor as an example, we will introduce the working principle of the pressure sensor.diode

Resistance pressure sensors are mainly composed of elastic elements, resistance plates, wires, and casings. When the measured pressure acts on the elastic element, it will deform, causing the resistance value of the resistor to change. The resistance value of this change can be transmitted to the circuit through wires and processed into standard electrical signals, such as 4-20mA, 0-5V, etc. This allows for the detection and control of the measured pressure.diode
