a) True The transducer changes the physical quantity into an electrical quantity. Photoconductive transducer, Thermocouple, Pressure gauge, strain gauge. The process of conversion of quantities is known as the transduction. Transducers and inverse transducers 4. a) Open loop transducers An inverse transducer is a device which converts a) Mechanical quantity to Electrical quantity b) Electrical quantity into mechanical quantity c) Electrical energy into thermal energy d) An electrical quantity into a non electrical quantity Ans : (d) Q8. Sanfoundry Global Education & Learning Series – Instrumentation Transducers. A mechanical force or displacement being converted into an electrical signal. View Answer, 6. Examples of transducer. A transducer is a device which converts one quantity into another quantity. View Answer, 9. An inverse transducer is a device which converts the electrical quantities (signals) into non-electrical signals e.g. An electric motor converts electrical energy into motion. Which of the following is an inverse transducer _____________ Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities. It is a precision actuator having an electrical input and low-power non-electrical output. c) Lead zirconate For example Piezoelectric crystal. Join our social networks below and stay updated with latest contests, videos, internships and jobs! 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). The name itself implies that the function of Inverse Transducer is inverse of the Transducer. According to another definition of transducer can be given as a device, which when actuated by the energy in one form, supplies energy either in the same form or in another form to a second transmission system.. The oscilloscope is used for converting the electrical signal into a physical displacement. The inverse transducer is the transducer which converts the electrical quantity into a non-electrical quantity. when an electric charge or voltage is applied to the surface of piezo-electric crystals, the dimensions of the crystal change due to deformation. 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 mechanical displacement. Definition: The transducer which converts input quantity into output having digital pulses is called digital transducer. Piezoelectric Transducer, current carrying conductor placed in an magnetic field. depends on the measurement of the physical quantities. c) Equality The transducers can be classified as per figure-1 above into following types. The transducer is a type of device that converts the physical quantities like pressure, brightness, displacement into an electrical quantity. A transducer is a device which, when actuated transforms energy from one form to another. Required fields are marked *. A transducer is an electronic device that converts energy from one form to another. a) Inverse proportionality In other words, the transducer is a kind of actuator which has an electrical input and the non-electrical output. Give an example. In a PMMC device what change will happen to torque, if flux density increased? PMMC devices are converters of _____________ Difference Between Transducer & Inverse Transducer. The process of converting one form of energy to … Definition and General Concept of Transducer Definition The transducer is a device which converts one form of energy into another form. The output quantity may or may not be electrical quantity. This set of Instrumentation Transducers Multiple Choice Questions & Answers (MCQs) focuses on “Inverse Transducers”. Simply we can say that it is a device capable of converting physical quantity into a proportional convenient form or state. View Answer, 8. Ex:-Resistive,inductive and capacitive transducers -An inverse transducer is defined as a device which converts an electrical quantity into a non-electrical quantity. Transducer – The device which converts the non-electrical quantity into an electric quantity is known as the transducer. Transducer 1. Prepared by: Engr:Temoor Abbas Transducers 2. The transducer has high electrical input and low non-electrical output. c) Electrical quantity to electrical quantity itself When the output quantity is electrical, then transducer is called as Electrical Transducer. Capacitive Transducers. It converts the measurand to a usable electrical signal. In simple words, the control action of the physical quantity is possible only when these quantities are correctly measured. 32) Define an Inverse transducer. In PMMC device, torque and number of turns have _______________ •In other word it is a device that is capable of converting the physical quantity into a proportional electrical quantity such as voltage or current. Which of the following cannot act as inverse transducer? examples are microphone, incandescent light and electric motor. View Answer, 7. The important characteristics of transducers are – Transfer Function. Self generating type transducers are _____ transducers. Transducer– The device which converts the non-electrical quantity into an electric quantity is known as the transducer. View Answer. d) Undetermined Inductive Transducers. Whereas, the inverse transducer changes the electrical quantity into the non-electrical quantities. An electrical transducer is a device which converts any physical quantity ... Read more Example of Inverse transducers are piezoelectric crystal. This can include loudspeakers and linear positioners are well as physical quantity to electrical signal devices. Example: • Shaft Encoders . In this type of transducers, an electrical signal is intentionally converted into some sort of physical change. But Piezoelectric Crystal can work as a transducer also. Whereas, the inverse transducer changes the electrical quantity into the physical quantity. Sensor and its components. Explanation: Transducers are devices which transfers measurand which will be a non-electrical quantity to electrical quantity. Input transducers and inverse transducers are the same. a) An electrical quantity into a non electrical quantity b) Electrical quantity into mechanical quantity c) Electrical energy into thermal energy d) Electrical energy into light energy. Is a device which detects or measures a physical property and … An inverse transducer is a device which converts a) b) Electrical quantity into mechanical quantity c) Electrical energy into thermal energy d) An electrical quantity into a non electrical quantity Ans : (d) 7. A transducer is a device that converts energy from one form to another.
