A pressure transducer is a device or system capable of sensing pressure signals and converting them into usable electrical signals according to certain rules.

Pressure sensors are typically composed of a pressure-sensitive element and a signal processing unit. According to different types of test pressure, pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

Pressure sensors are a commonly used type of sensor in industrial practice, widely applied in various industrial automatic control environments, including hydropower and water conservancy, railway transportation, intelligent buildings, production automatic oil wells, electricity, ships, machine tools, pipelines, and many other industries.
