Required fields are marked *. The transducer is classified by the transduction medium. The output signal is obtained from the physical input quantity. Active transducers are the type of transducer that does not make use of any external source in order to generate the output. Select one: O True False The transducer, which can produce one of the electrical quantities such as voltage and current is known as active transducer. 13 points Self generating type transducers are _____ transducers * Ask for details ; Follow Report by Rahulrapole4701 28.04.2019 Log in to add a comment What do you need to know? The energy requires for generating the output signals are obtained from the physical quantity which is to be measured. The mass applies on the crystals induces an output voltage. The active transducer is also known as the self-generating transducer because they self-develop their electrical output signal. Solution for Active transducers are self generating type transducers. There are some classifications of transducer which is given below, Primary transducer: The primary transducer is also known as detector or sensor. The piezo crystal has the special property because of which when the force is applied to the crystal, they induce the voltage. What are the advantages and disadvantages of electrical transducer. Answer to Active transducers are self generating type transducers. voltage or current) which is proportional to the quantity under measurement. It is also called self-generating transducer, since it doesn’t require any external power supply. Active Transducer – The transducer which does not require the external power source is known as the active transducer. Such type of transducer develops theirs owns voltage or current, hence known as a self-generating transducer. Example: The Piezo electrical crystal is the example of the natural active transducer. The base provides the acceleration due to which the voltage is generated. The output signal is sent to the conditioning device where the signal is attenuated, filtered, and modulated. The circuit o/p can be directly adjusted against the input value. Physics. The crystal is sandwiched between the two metallic electrodes, and the entire sandwiched is fastened to the base. There are various electrical and electronic components are used to build the circuits and projects for engineering students. These transducers do not need any external source of power for their operation. Subscribe to our newsletter below and never miss the latest technology, news and articles. In general, the process of transduction involves the conversion of one form of energy into another form. Pages 49. The block diagram of active transducer is shown in below figure. The transduction medium may be resistive, inductive or capacitive depends on the conversion process that how input transducer converts the input signal into resistance, inductance and capacitance respectively. Secondary School. The above mention transducer is known as the accelerometer which converts the acceleration into an electric voltage. What are the advantages and disadvantages of piezoelectric transducer? ). Self generating type transducers are _____ transducers.
