Question Paper
Explain the function of optical strain gauge with neat sketch.
(b) Describe strain gauge rosettes with suitable diagram.
2.(a) What types of electromechanical devices are available for vibration measurement Explain anyone method. A single strain gauge having a resistance of 100 ohms and a gauge factor of 20 is mounted on a steel cantilever beam and connected in series with a 100 ohms ballast resistor and a 12 volt battery. The bending stress at the gauge fluctuates from 0 to 19·62 x 10^8 N/m^2. Assume modulus of elasticity 20·60 x 10^10 N/m^2. Compute the corresponding variation in output voltage. Can this variation be magnified to full scale on an oscilloscope The oscilloscope has sensitivity of 10 mV/cm of trace deflection and a screen length of 10 cm.
3.(a) Explain the causes of vibration in machines. What are their harmful effects and remedies Name various types of instruments used for speed measurement. Explain the working of magnetic tachometer.
4.(a) Explain anyone method for non-contact type temperature measurement.
(b) What are thermocouples? Explain different types of materials used in thermocouples, and their properties.
5.(a) Name different techniques available for elemental analysis. Explain anyone of them.in detail.
(b) List various methods that are available for level measurement. Explain briefly level measurement by electrical conductivity method.
6.(a) Define sensitivity, drift, dead zone, accuracy, errors and range.
Differentiate between the following:
Random and Systematic Errors
(ii) Static and Dynamic characteristics
7. Write short notes on the following: Thickness Sensor
Digital Transducer Infrared Gas Analyser Robotics Level Measurement Method Stress Measurement by Photoelastic Method Generalised Data Acquisition System
