Powered by, One of the major differences between the transducer and the inverse transducer is that the transducer changes non-electrical quantity into the form of electrical quantity. As a primary transducer, it converts physical quantity into mechanical signal. The output quantity may or may not be electrical quantity. Measurement is an important subsystem in any major system, whether it may be a mechanical system or an electronic system. Transducers • A Transducer is a device which converts one form of energy into another form. The mechanical signal produced by the primary transducer converts into an electrical signal by the electrical device and it is called a secondary transducer. Inverse transducer is defined as a device which converts an electrical quantity into a non electrical quantity: A piezoelectric crystal acts as inverse transducer because when a voltage is applied across its surfaces, it changes its dimensions causing a … ©2017-2020 ecstuff4u.com The content is copyrighted and may not be reproduced. The other differences between the transducer and inverse transducer are shown below in the comparison chart. The transducer transforms the non-electrical quantity into the electrical quantity. Examples: The analogue ammeter and the voltmeter convert the current into a displacement. So, the distance between these two metal plates and positions of the plates can change the capacitance. There are various electrical and electronic components are used to build the circuits and projects for engineering students. Hence it converts any quantity to be measured into usable electrical signal. The output of the transducer is the electrical quantity while the output of the inverse transducer is always the non-electrical quantity. Required fields are marked *. Prepared by: Engr:Temoor Abbas Transducers 2. The photoconductive cell, thermocouple, pressure gauge are the examples of the non-electrical quantities. Floppy disk is a magnetic storage medium for a computer system. converts the measurand to a usable electrical signal. • Alternatively, a Transducer is defined as a device which provides usable output response to a specific input measured which may be a physical quantity. Q. . when an electric charge or voltage is applied to the surface of piezo-electric crystals, the dimensions of the crystal change due to deformation. •Transducers … The inverse transducer is the transducer which converts the electrical quantity into a form of non-electrical quantity. The oscilloscope is used for converting the electrical signal into a physical displacement. It is similar to  UT... Conduit wiring is a system where the cable is enclosed in metal or some plastic tubes. For example, in servomechanism, the position of the shaft is controlled by measuring the exact position of the shaft. The cell with low traffic speed is called as micro-cells and large high-speed traffic called macro-cells. The transducer changes the physical quantity into an electrical quantity. Here this article give the information about the main key difference between a. These signals production can depend on the effects of resistive, capacitive and inductive. Here when the Voltage is applied it results in the displacement to be produced or the deformation in the Piezoelectric material thereby imparting a mechanical movement(Physical quantity). Sensors used in automobiles to detect touch and activate the siren.
