Electrical Transducer: Types, Working and Its Advantages

  A Transducer  is a device that converts variations into a measurable physical quantity i.e., pressure into Electrical signals or the other way round. Strain Gauge, Hydraulic and Pneumatic are the commonly used Transducers. Strain Gauge is the used in numerous industries like Automobile, Medical and Weighing etc. Load cells are also a type of force Transducer. The process of converting forces into electrical signals is called Transduction.   An electrical transducer is a kind of transducer which gives electrical energy as an output. It converts any type of energy into an electrical signal. The energy input may be heat, light, or sound and the electrical signal can be frequency, current or voltage. These signals production can depend on the effects of resistive, capacitive and inductive. The nonelectrical quantities can be measured by using a detector which changes the physical quantity to a displacement to activate the transducer.   Types of Electrical Trans...
