In retardation type measuring lag the instrument responds after an unspecified dead time lag. For example, a Pressure Transducer is a transducer that converts pressure into electrical signal. the given non-electrical energy is converted into an electrical energy. The main principle of the temperature transducer is to measure the heat and transfer the information after converting it into the readable form. Classification of Transducer. Transducers are electric or electronic devices that transform energy from one form to another. a) True Answer: Option C . An active transducer is one that does not require any power source in order to function. A foam like material, having a resistance that varies depending on how much it is compressed, is known as are examples of transducers. For example, for a transducer used for temperature measurement, sensitivity will be expressed in mV/’ C. A high sensitivity is always desirable for a given transducer. d) Statical error d)All of these. Based on its working, transducers are classified into the following parts. Example of transducers are: thermocouple; microphones ; The transducer consists of a sensor and signals conditioning circuits and finds application in communication systems to convert the electricity to electromagnetic waves. d) Photovoltaic cell Which among the following transducer is an example of active transducer? This doesn’t mean that these types of transducers don’t require power at all. Passive Transducers. Following are the examples of active transducers. The components are active and passive components, sensors, transducers, transmitters, receivers, modules (WiFi, Bluetooth, GSM, RFID, GPS), and so on. Answer : b) Is the answer (Amplifier) Solution : A transducer is a device that converts one form of energy into another. The transducer, which can produce one of the electrical quantities such as voltage and current is known as active transducer. View Answer, 13. Example of active transducer is piezoelectric crystal. It is also called a self-generating transducer it generates its own voltage or current. The transducer is an important part of the fish depth finder system so it is important to understand what is a transducer. A measurement system consists of sensors, actuators, transducers and signal processing devices. View Answer, 2. A transducer is an electronic device that converts energy from one form to another. Note that, the output is not continuous rather it is in the form of pulse which means that it is discrete. Hence the transducer will just convert the energy from one form to another and all the remaining work is done by the additional … Which of the following is not a characteristic of an ideal transducer? To practice all areas of Mechatronics, here is complete set of 1000+ Multiple Choice Questions and Answers. Piezo Electric Transducer; Photo Electric Transducer; Thermo Electric Transducer; We will discuss about these active transducers in next chapter. This process mainly includes a sensing element to sense the i… Active transducer: The transducer which does not require an external electrical power supply to convert a physical parameter into an electrical quantity. a) True Note that a transducer and a sensor are not the same. a) True As shown in the figure, active transducer will produce an electrical quantity (or signal), which is equivalent to the non-electrical input quantity (or signal). Note that any device which is able convert one form of energy into another form is called as a transducer. Selection of a transducer is one of the most important factors which help in obtaining accurate results.
