â¢ Transducers and sensors are physical devices that are used in electrical, electronic and many other types of gadgets and appliances. â¢ Transducers are used to convert one energy type into another while sensors measure energy levels and convert them into electrical signals that can be measured digitally.
(November 2013). A transducer is a device that converts one form of energy to another. Energy types include (but are not limited to): electrical, mechanical, electromagnetic (including light), chemical, acoustic, and thermal energy.ransducers are widely used in measuring instruments. An actuator is a transducer that accepts energy and produces the kinetic energy of movement (action). The energy supplied to an actuator might be electrical or mechanical (pneumatic, hydraulic, etc.).
