The transducers can be classified on the basis of the output which may be a continuous function of time or the output may be in discrete steps. Resistive sensors generally include potentiometer type, contact variable resistance type, resistance strain gauge type and piezoresistive sensor. A transducer is an electrical device, used to convert one form of energy into another form. Close suggestions. Active and passive transducers. On the basis of transduction principle used. Classification of Transducer Once certain basic functions common to all instruments have been identified, then we see if it is possible to make some generalization on how these functions may be performed. Application of the principles to the classification of temperature sensors is outlined as an example. • Antenna: is the most basic transducer and can be made from a simple In the first classification of the sensors, they are divided in to Active and Passive.

Sign In Join. endobj en Change Language. CLASSIFICATION OF TRANSDUCERS The transducers can be classified as: I. into a signal which can be measured electrically.Sensor can be defined as an element that senses in one form of energy to produce a variant in same or another form of … But if the physical force is converted into an electrical signal, then their value is easily measured with the help of the meter. Learn more about Scribd Membership. A transducer is a device that is used to convert a physical quantity into its corresponding equivalent electrical signal. Transducers which require an external power source for their operation is called as a passive transducer. 1. Introduction Nowadays, the importance of a monitoring and regulating many different parameters in areas such a food industry (aMonoÅ¡ík et al. 10. The name of each class is keyed to the transduction mechanism, but its explanation is given along with the description of the transducer. Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. Classification and taxonomy of the many sensors has been developed using the principles of life sciences methods. Classification of Transducers based on transduction Principle. PDF | On Dec 6, 2017, G R Sinha published Introduction and Classification of Sensors | Find, read and cite all the research you need on ResearchGate Upload. 2. 1. This will make the measurement system very compact. CLASSIFICATION & SELECTION OF TRANSDUCERS We have tabulated the class of transducers and some important measurands are mentioned. The following classification of sensors may already be used by an expert in the subject but this is a very simple classification of sensors. Moreover, the beam shape is convex (see picture below) and the transducer is good for in-depth examinations. Classification of transducers The transducers can be classified as: I. When a transducer converts a measurable quantity (sound pressure level, optical intensity, magnetic field, etc) to an electrical voltage or an electrical current we call it a sensor.

With the potential for as many as thirty parameters affecting measurement It is quite difficult to determine the exact magnitude of the physical forces like temperature, pressure, etc. Analog and Digital Transducers . The speed of response of the transducer should be as high as practicable. A transducer is a device which transforms a non-electrical physical quantity (i.e. Because of this broad definition, transducers come in many varieties converting many different types of energy. 4 0 obj In general, the process of transduction involves the conversion of one form of energy into another form. Download with Google Download with Facebook. Inertial Measurement Unit data is used for a variety of tasks. In most electrical systems, the input signal will not be an electrical signal, but a non-electrical signal like voice, pressure, et cetera. ó“æ6þùc—v€Þ@K/Õ ÊóŒ#eþõ¥Eã—ô¢ˆß0ëþó瞘6Ý»mœ®Þ72:´nÎq#ՊÌ$ðŒ #Ÿ)5Š+*«Å”  kÒžÉÔĽ°Ú›}Œh„yË!ipÙkSmÙwÓؑ¼¢¡¾ÛÖS$«HÜ£L{žBËÉÍpu‡‹µŸ‹»}c$ îh ¶“Ʊâ3NÃxî%Ž}¹ÑîÐÿr:•â , —´]ø˜?.™îþqAÜKrè´¾x^áî‰Ü.
