Pressure chips, also known as pressure sensors or pressure transducers, are electronic devices used to measure and monitor pressure changes in various industrial and commercial applications. They are typically made of semiconductor materials such as silicon and employ micro-electromechanical system (MEMS) technology to convert pressure changes into electrical signals. The electrical output from the chip can then be processed and displayed on a device such as a computer or mobile phone for analysis. Pressure chips are commonly used in applications such as automotive, aerospace, and medical equipment, as well as in industrial processes such as oil and gas production and manufacturing.
