A transducer is a device that converts one form of energy into another. Common transducers include thermocouples and resistance temperature detectors that convert temperature into electrical signals. Piezoelectric transducers use crystals to convert mechanical stress into electrical voltages. Pressure transducers specifically measure pressure by converting the amount of pressure on a gas or liquid into an electrical signal. These can generate electricity from the force of vehicles. Temperature transducers measure temperature and convert it into electrical or other forms of energy. Ultrasound transducers send and receive ultrasound waves to measure distances that are difficult to access through conventional means.

2.  A transducer is a device that converts energy from one form to
another. Usually a transducer converts a signal in one form of energy to
a signal in another.
 Example:
 Thermocouples
 Temperature transducers
 Resistance temperature detector
 Thermistor
 Resistive position transducers

4.  Piezoelectricity (also called the piezoelectric effect)
is the appearance of an electrical potential (a voltage,
in other words) across the sides of a crystal when you
subject it to mechanical stress (by squeezing it)
 convert mechanical energy into electrical energy

5.  Pressure transducer is a special kind of sensor that alters the pressure forced
into electrical signals. These transducers are also called as pressure indicators,
manometers, piezometers, transmitters, and pressure sensors.
 Pressure transducer is used to measure the pressure of the specific quantity like
gas or liquid by changing the pressure into electrical energy.
 These transducers can be used for generating an electrical power under the
speed breakers on the highways or roads where the force of the vehicles can be
converted into electrical energy.

7.  convert the temperature of a device into another quantity
like electrical energy or pressure or mechanical energy
 Used to measure the temperature of the air such that to
control the temperature of several control systems like air-
conditioning, heating, ventilation, and so on.

8.  The main function of the ultrasound transducer is to convert electrical
signals to ultrasound waves.
 The areas which are hard to find, such as pressure areas, very high
temperature, using conventional methods the measurement of the
distance is not a simple task. So, this transducer based measuring
system can be used in this kind of zone.
