It has rugged construction. When the output quantity is electrical, then transducer is called as Electrical Transducer. Hence it converts any quantity to be measured into a usable electrical signal. -> With the advent of IC technology, the electronic systems have become extremely small in size, requiring small space for their operation. Advantages and disadvantages of piezoelectric transducer When an external force is applied to this transducer, the produced voltage that can be measured easily. The electrical output can be easily used, transmitted, and processed for the purpose of measurement. Transducer or Inverse transducer: Transducers convert non-electrical quantity to electrical quantity.Inverse transducers convert electrical quantity to a non electrical quantity, Transducer may be classified as active or. -> The electrical systems can be controlled with a very small level of power. - 9012426 Classification of Transducers based on transduction Principle. Starting in the mid-1990s, sensors and transducers started to move from purely analog operation to digital protocols, signal processing, and interfaces. This transducer is very useful for telemetry applications. 8. In general, the process of transduction involves the conversion of one form of energy into another form. Advantages of LVDT High Range : LVDT can be used for measurement of displacements ranging from 1.25 mm to 250 mm. For example, a thermocouple is an active transducer. ⦁ Some transducers contain the mechanical as well as electrical device. Transducers external to heated buildings may require freeze protection.
