Lecture Notes Mechatronics (M.Tech, Design Dynamics) 14 | P a g e Module-II Sensors and Transducers: An introduction to sensors and Transducers, use of sensor and transducer for … Your use of the MIT OpenCourseWare site and materials is subject to our Creative Commons License and other terms of use. A passive sensor has no power supply and all the energy it delivers to the next stage (the signal conditioning) is drawn from the measurand. Range & Span- a. Range & Span- a. Here, the output is usually an ‘electrical quantity’ and measurand is a ‘physical quantity, property or condition which is to be measured’. 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 The sensors can be classified as active and passive. (PDF - 4.4MB) 4: Pressure and force (PDF - 3.7MB) 5: Pressure, strain and piezoelectrics (PDF - 10.2MB) What is open collector, TTL level. The full range of a sensor can be limited by compression or by clipping. /P -60 /V 1 /Length 40 >> endobj 4677 0 obj << /S 1740 /L 2976 /Filter /FlateDecode /Length 4678 0 R >> stream Contact sensors Displacement , position and proximity sensor Non-contacting sensors The presence in the vicinity of the measured object cause change in air pressure or change in inductance or capacitance The movement of the sensor element’s is used to cause a change in electrical volatge, resistance, capacitance or mutual inductance The commonly MIT OpenCourseWare is a free & open publication of material from thousands of MIT courses, covering the entire MIT curriculum. It is defined as an element which produces signal relating to the quantity being measured. Gate metal is replaced with an ion selective membrane. 0000000908 00000 n Range The region between the limits within which an instrument is designed to operate for measuring, indicating or recording a physical quantity is called the range of Explore materials for this course in the pages linked along the left. Thus you will be seeing a lot of BJTs when you work with sensor interfaces. •Active Transducer - one which requires external power. Any instrumentation system must include an input transducer (sensor), sensor Bridge circuit-Conductometry where the conductance of the cell is measured 5 cm 5 mm 10mm. ˘! It comprises of three ports. Sensor manufacturers recognize these pin standards, so you don’t have to deal with all sorts of different communication protocols with interfacing with a sensor Send to friends and colleagues. It comprises of three ports. 0000004351 00000 n Download PDF of Sensors And Transducers Note offline reading, offline notes, free download in App, Engineering Class handwritten notes, exam notes, previous year questions, PDF free download PDF | Remote sensing is the acquisition of information about an object without coming in physical contact of that object. Thus you will be seeing a lot of BJTs when you work with sensor interfaces. Knowledge is your reward. – Sensor’s electrical properties • Amplifier, optoisolator e.g. •Resolution - how fine of a measurement can we make? • A sensor acquires a physical quantity and converts it into a signal suitable for processing (e.g. We don't offer credit or certification for using OCW. •Active Transducer - one which requires external power. Thus in the case of, say, a variable inductance displacement element, the quantity being measured is displacement and the sensor transforms an input of displacement into a change in inductance. 0000000654 00000 n Made for sharing. 0000040662 00000 n Freely browse and use OCW materials at your own pace.
