Pressure sensor is a device that senses a pressure signal and converts the pressure signal into a usable output electrical signal (4-20mA/0-20mA/0-5V/1-5V/RS485/HART).
Pressure sensors are usually composed of pressure sensitive components and signal processing units. According to different types of test pressure, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.
Pressure sensor is the most commonly used sensor for air/oil/water/hydraulic pressure measurement. It is widely used in various industrial automation control environments, such as involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil well, electric power, ship industry, machine tools, pipelines and many other industries.
