Final answer:
A piezo transducer is used to measure automotive engine pressure. It converts mechanical stress into an electrical signal. The correct answer is C.
Step-by-step explanation:
The device used to measure automotive engine pressure is a piezo transducer. It is a sensor that uses a piezoelectric material to convert mechanical stress into an electrical signal. When placed in the engine, it can measure the pressure changes within the cylinders, allowing for monitoring and diagnosis of the engine performance.
A piezo transducer is a device typically used for measuring automotive engine pressure, while industrial manometers may also be used for this purpose. Bourden tubes and Pirani gauges are less common in automotive applications.
Automotive Engine Pressure Measurement Device
Among the devices listed, a piezo transducer is commonly used to measure automotive engine pressure. Industrial manometers can also be utilized for this purpose, while the Bourden tube and Pirani gauge are not typically used in automotive applications. A bourden tube is often used in general pressure measurement applications. A Pirani gauge is specialized for measuring low vacuum pressures. An industrial manometer, on the other hand, measures pressure with a fluid column and is used in various industries, but is less common in automotive settings.
