Question

A conventional Altimeter is

• A. pressure transducer
• B. velocity transducer
• C. temperature transducer
• D. density transducer

Hint:

Altimeters sense static pressure and display corresponding altitude.

Answer 1

The Correct Option is A

A conventional altimeter is an instrument used to measure an aircraft's altitude. It operates based on the principle that atmospheric pressure decreases with an increase in altitude. Thus, the altimeter is a type of pressure transducer because it measures atmospheric pressure variations to determine altitude. Among the given options:

• Pressure transducer - Correct. Altimeters use atmospheric pressure to estimate altitude.
• Velocity transducer - Incorrect. Used for measuring speed, not altitude.
• Temperature transducer - Incorrect. Used for measuring temperature.
• Density transducer - Incorrect. While related to pressure and altitude, directly measures density rather than altitude.

Therefore, the correct option is that a conventional altimeter is a pressure transducer.
