Transducer types[ edit ] Mechanical and electrical transducers[ edit ] Transducers that convert physical quantities into mechanical ones are called mechanical transducers; Transducers that convert physical quantities into electrical are called electrical transducers.

Examples are a thermocouple that changes temperature differences into a small voltage, or a Linear variable differential transformer LVDT used to measure displacement.

Sensors and actuators[ edit ] Transducers can be categorized by which direction information passes through them: A sensor is a transducer that receives and responds to a signal or stimulus from a physical system. An actuator is a device that is responsible for moving or controlling a mechanism or system.

It is controlled by a signal from a control system or manual control.

It is operated by a source of energy, which can be mechanical force, electrical current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion.

An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple a fixed mechanical or electronic systemsoftware -based e. An example of an inherently bidirectional transducer is an antennawhich can convert radio waves electromagnetic waves into an electrical signal to be processed by a radio receiveror translate an electrical signal from a transmitter into radio waves.

Another example is voice coilswhich are used in loudspeakers to translate an electrical audio signal into sound and in dynamic microphones to translate sound waves into an audio signal.

The signal is modulated by the sensor to produce an output signal. For example, a thermistor does not generate any electrical signal, but by passing an electric current through it, its resistance can be measured by detecting variations in the current or voltage across the thermistor.

Such examples are a photodiodeand a piezoelectric sensor, thermocouple. This is the ratio between the largest amplitude signal and the smallest amplitude signal the transducer can effectively translate.

This is the ability of the transducer to produce an identical output when stimulated by the same input.

What is Signal Conditioning?

All transducers add some random noise to their output. In electrical transducers this may be electrical noise due to thermal motion of charges in circuits. Noise corrupts small signals more than large ones.

This is a property in which the output of the transducer depends on not only its current input but also its past input. For example, an actuator which uses a gear train may have some backlashwhich means that if the direction of motion of the actuator reverses, there will be a dead zone before the output of the actuator reverses, caused by play between the gear teeth.

Applications[ edit ] Transducers are used in electronic communications systems to convert signals of various physical forms to electronic signalsand vice versa.

In this example, the first transducer could be a microphoneand the second transducer could be a speaker. Antennae β€” converts propagating electromagnetic waves to and from conducted electrical signals magnetic cartridges β€” converts relative physical motion to and from electrical signals Hall effect sensors β€” converts a magnetic field level into an electrical signal Electrochemical:NESS Corporation APCS Division - About Us.
