A pressure transducer is a vital sensing device used to measure and convert pressure into an electrical signal. It typically consists of a sensitive diaphragm or membrane that deforms in response to applied pressure, causing a change in electrical resistance, capacitance, or voltage output. This change is then converted into a measurable signal proportional to the applied pressure. Pressure transducers come in various types, including piezoresistive, capacitive, and piezoelectric, each offering specific advantages in terms of accuracy, sensitivity, and durability. They are widely utilized in industrial, automotive, aerospace, and medical applications for monitoring and controlling pressure in systems such as hydraulic and pneumatic systems, engines, pipelines, and medical devices. Pressure transducers play a crucial role in ensuring safe and efficient operation across numerous industries.
