Course TitleTransducers
Credit12
Course ContentTransducers and their characteristics: Definition of terminologies – Generalized performance characteristics – range – resolution – linearity – overload factor – accuracy – precision – static and dynamic – rise time – fall time – settling time– slew rate – frequency response – bandwidth – modelling – Classification – ingress protection – vibration isolation – passive – active.Resistive Transducers: Resistance potentiometer – noise – resolution – signal conditioning – strain gauges – associated electrical circuitry – temperature compensation – load cells – torque and pressure measurement using strain gauges –resistive temperature device (RTD) – three-lead arrangement – thermistors – linearization - hot-wire anemometers – time constant improvement – measurement of direction of flow – peizo resistive transducers.5 Experiments on signal conditioning applied to transducersInductive Transducers: Self-inductance transducers – transverse armature and plunger type – sensitivity and linearity – signal conditioning circuits – choice of components – linear variable differential transducer (LVDT) – lead and lag compensation.Capacitive Transducers: Single – push-pull – angle transducer – humidity sensor – parasitic effects – solutions – signal conditioning circuits.Miscellaneous transducers: Peizo electric – signal conditioning – thermo couples – theory – mass-spring accelerometer – force-balance.Applications of transducers: Measurement of displacement (linear and angular) – velocity – acceleration – force – torque – pressure – flow – temperature.
