Pressure sensors are devices that measure the pressure of gases or liquids. They convert the physical pressure into an electrical signal, which can be read and interpreted by various systems. These sensors are commonly used in industries such as automotive, aerospace, and manufacturing to monitor and control processes. There are different types of pressure sensors, including piezoelectric, capacitive, and strain gauge sensors. Each type operates on different principles and is suited for specific applications. Pressure sensors play a crucial role in ensuring safety and efficiency in systems like HVAC, medical devices, and oil and gas operations.
