EI010 405 Electronic Instrumentation Teaching scheme 3 hours lecture and 1 hour tutorial per week Credits: 4 Objectives 1. 2. 3. 4. 5. To equip the students to apply all types of common electrical and electronic instruments with the knowledge about the construction and working of the instruments. To provide the details of various electronic instruments which are used to measure current, voltage, power, energy, resistance, capacitance and inductance. To introduce the construction and working of different types of ammeters, voltmeters and bridges. A clear idea has been given about digital electronic instruments which are used to measure voltage, frequency, period, total count etc. An exposure is given to the student about signal generation, display and recording devices which help in analysing and displaying the data. Module 1 (12 Hours) Measurement of electrical parameters: Types of ammeters and voltmeters – Principle of operation , construction and sources of errors and compensation of d’Arsonval galvanometers- PMMC Instruments – Moving Iron Instruments – Dynamometer type Instruments – Rectifier type ammeters and volt meters. Electro dynamic type Watt meter- Single phase induction type Energy meters. Calibration of Wattmeter and Energy meters. Module 2 (12 Hours) Resistance measurement:: Measurement of low, medium and high resistance- Wheatstone bridge, Kelvin double bridge, series and shunt type Ohm meter- Meggar –Earth resistance measurement. Measurement of Inductance and capacitance:- Maxwell Wein bridge, Hay’s bridge and Anderson bridge - Campell bridge –Owen’s bridge- Measurement of capacitance:- Schering bridge . Module 3 (12 Hours) Analog meters :– DC volt meters- chopper amplifier type – peak responding volt meter- true RMS volt meter- Vector voltmeter -calibration of DC instrument --Ammeters – Multi meter – Power meter – Q-meter . Digital Instruments : Digital method for measuring frequency, period – Phase difference – Pulse width – Time interval, Total count. Digital voltmeter –– DMM – Microprocessor based DMM- Digital tacho meter- Digital ph meter. Module 4 (12 Hours) Signal generators and analyzers : Sine wave generator – Sweep frequency generator, Pulse and square wave generator – Function generator – Wave analyzer – Applications – Harmonic distortion analyzer – Spectrum analyzer – Applications – Audio Frequency generator – Noise generator.
