The communication can be … Before going in to the details of What is a Sensor, What are the Different Types of Sensors and Applications of these different types of Sensors, we will first take a look at a simple example of an automated system, which is possible because of Sensors (and many other components as well). Difference between Sensor and Transducers Transducer – these are elements when subjected to physical change experience a related change. Looks like you’ve clipped this slide to already. There are various electrical and electronic components are used to build the circuits and projects for engineering students. a speaker) 16 17. TUTORIAL 2 – SENSORS AND PRIMARY TRANSDUCERS This tutorialprovides an overview of instrument sensors used in process and automatic control. TRANSDUCERS Transducers as already defined , is a device that converts a non electrical quantity into an electrical quantity. a microphone) • Actuator: • converts an electrical signal to a physical output (opposite of a sensor, e.g. Sensor vs Transducer Sensor and Transducer are physical devices that are used in electrical, electronic and many other types of gadgets and appliances. • Ideally there should be a straight line relationship so that equivalent changes in input produce the same order of change in output no matter where within the sensor’s range these occur. Different Types Of Sensors With Their Applications. Physical quantities can be temperature, pressure, light, current, weight etc. Difference between sensor and transducer is something that many people are often confused with and needs to be brought into light. Chapter 2 Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. 4. Important characteristics of sensors and transducers are listed below: Input characteristics Transfer characteristics Output characteristics Input Characteristics of Sensors Range: It is the minimum and maximum value of physical variable that the sensor can sense or measure. Transducers or measurement systemsare not perfect systems. Induced EMF is given as Where B is the magnetic induction, l is the length of the conductor, and V is the velocity of the moving conductor. 11. digital tachometer) Sensor. Chapter 2 Sensors and Transducers 1 2. Sensor A Device that receives and respond to a signal or stimulus 4. Some of the commonly used signal - Pressure transducers that use a bend tube are called Bourdon tube. This produces a voltage, which is proportional to the rate of change of flux. Sensors and Transducers introduction and applications are described in this slide. 3. 25633083 sensors-and-transducers 1. II-Characteristics of different types of sensors a) Active vs. Sensors – the term sensor is used for an element which generates a signal which is proportional to the quantity being measured. It is useful to anyone studying measurement systems and instrumentation but it is provided mainly in support of the EC module D227 – Control System Engineering. Introduction to sensors & transducers by Bapi Kumar Das, Pe 4030 ch 2 sensors and transducers part 1 final sept 20 2016, No public clipboards found for this slide, Student at kakatiya institute of technology and science. A sensor is a sophisticated transducer in the sense that it contains some signal conditioning circuits capable of amplifying and refining the weak and raw signal that is available at the output of the transducer. Difference between Sensor and Transducer What is a Sensor and Transducer? ECE 445: Biomedical Instrumentation Sensors p. 1 Sensor Calibration Transducers • Transducer • a device that converts a primary form of energy into a corresponding signal with a different energy formsignal with a different energy form • Primary Energy … You can change your ad preferences anytime. Because sometimes transducers are discovered in sensors.The primary distinction between the sensor and the transducer is that the sensor is a physical device that senses a physical quantity and then transforms it into signals that an instrument or the user can read. This signal must be produced by some type of energy, such as heat, light, motion, or chemical reaction. The negative sign indicates that the direction of induced EMF and the direction of induced current are in the opposite direction. See our User Agreement and Privacy Policy.

The transducer, which converts non-electrical form of energy into electrical form of energy is known as electrical transducer.The block diagram of electrical transducer is shown in below figure.. As shown in the figure, electrical transducer will produce an output, which has electrical energy. Sensors and Transducers 2 3. 1. 67. Now customize the name of a clipboard to store your clips. Transducers convert one form of energy into another. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. after any offsets have been subtracted from the sensor response. The sensor is a device, that senses a physical quantity and converts it into an analogue quantity which can be measured electrically such as voltage, capacitance, inductance and ohmic resistance.The output needs to be operated, interfaced & regulated by the system designer. Typical applications of different types of sensors such as application of Speed sensor for synchronizing the speed of multiple motors, Temperature sensor application for industrial temperature control, application of the PIR sensor for automatic-door-opening system, Ultrasonic sensor application for distance measurement, etc., are … All these and many other automation tasks are possible because of Sensors. Sensors. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The inverse magnetic effect is also true. change in resistance) or active (output is a voltage or current level) Sensors can be . • A sensor acquires a physical quantity and converts it into a signal suitable for processing (e.g. When current pa… We have tried to touch upon the various points of difference between sensors and transducers in this article. No public clipboards found for this slide. When an electrical conductor moves in a magnetic field, it changes the magnetic flux through the conductor. Sensor/transducers specifications. 1. PRINCIPLES OF SENSORS & TRANSDUCERS • Linearity • The relationship between output and input is a key parameter for sensors and transducers. A measurement system consists of sensors, actuators, transducers and signal processing devices. Transducer, Sensor, and Actuator • Transducer: – a device that converts energy from one form to another • Sensor: – converts a physical parameter to an electrical output (a type of transducer, e.g. See our Privacy Policy and User Agreement for details. A pressure transducer is used to convert a certain value of pressure into its corresponding mechanical or electrical output. The sensor senses the physical change across the surrounding whereas the transducer transforms the one form of energy into another.

Transducers Transducer a device that converts a primary form of energy into a corresponding signal with a different energy form Primary Energy Forms: mechanical, thermal, electromagnetic, optical, chemical, etc. Matthew Spencer. thermocouples) or . In general, the process of transduction involves the conversion of one form of energy into another form. Now customize the name of a clipboard to store your clips. And transducers – which are the opposite of sensors T… See our User Agreement and Privacy Policy. Sensors can be passive (e.g. Types The types of pressure sensors are differentiated according to the amount of differential pressure they are able to measure.
