Title: Distinguish between a transducer and a sensor.
Course: Principles of Technology II (03153-II) > Section: UNIT 11: TRANSDUCERS

Distinction should state the following:

- A sensor measures a physical quantity (e.g., light, sound, or space) and converts the information into a readable format; it does not divert energy from its principal operation.
- A transducer converts energy from one form to another; the goal of a transducer is efficiency in the conversion of energy.
- Most transducers are sensors.

Process/Skill Questions:

- What is the difference between a transducer and a sensor?
- What is the purpose of a transducer?
- How can transducers be classified (i.e., according to the form of energy on their input side)?
- What devices are used to measure the output of a transducer?
- How much energy does a transducer typically consume?
- Why is a transducer typically read with a mechanical gauge or an electrical meter?
