Transducer
Transducers are converters used to convert energy from one shape to another and convert input energy into output energy, like converting electrical energy to mechanical and vice versa. The use of Transducers is very wide. The efficiency element is one of the important factors in the measurement of transducers, which is calculated based on the ratio of output energy to input. It cannot be said that the transducers have a 100% efficiency, but the higher the output energy than the input power, the more efficient the transducer can be.
What is a transducer?
A transducer is a device that converts energy from one form to another. In engineering and industrial fields, a transducer is usually referred to as a device that converts a physical quantity (such as pressure, temperature, flow, or force) into a measurable electrical signal (such as voltage or current).
Transducers are used in many industries as measurement and control instruments and play a key role in automation systems due to their high accuracy, sensitivity, and reliability.
