Classification of Active Transducers
Active transducers convert one form of energy into another form and require an external power source to operate. They are classified into four types as follows:
1. Thermoelectric Transducers - These transducers convert temperature differences into electrical voltage. Thermocouples and thermopiles are examples of thermoelectric transducers.
2. Piezoelectric Transducers - These transducers convert mechanical stress into electrical energy. They are used in microphones, accelerometers, and pressure sensors.
3. Photoelectric Transducers - These transducers convert light energy into electrical energy. Photodiodes, phototransistors, and solar cells are examples of photoelectric transducers.
4. Magnetic Transducers - These transducers convert magnetic energy into electrical energy. They are used in magnetic pickups, speed sensors, and magnetic flow meters.
Conclusion
Active transducers are an important type of transducer that requires an external power source to operate. They are classified into four types based on the type of energy they convert. Understanding the different types of active transducers and their applications is crucial for selecting the right transducer for a particular application.
