Question

Quizplus · Accepted Answer

An input transducer is a device that converts a non-electrical quantity (such as temperature or pressure) into an electrical quantity (such as voltage or current), which can then be measured or processed by electrical equipment. Transformers are used to change the voltage level of an electrical signal, but they do not convert a non-electrical quantity into an electrical quantity. Output transducers convert an electrical signal into a non-electrical quantity. Converters can refer to a wide range of devices that change one form of energy into another, but it is not specific enough to refer to a device that converts a non-electrical to an electrical quantity.
