1. Measurement of force torque, velocity (7)
Electric balance – different types of load cells – magnets – elastics load cell-strain
gauge load cell-different methods of torque measurement, strain gauge, relative regular
twist-speed measurement-revaluation counter- capacitive tacho-drag up type tacho
D.C and A.C tacho generators – stroboscope.
2. Measurement of acceleration, vibration and density (8) Accelerometers – LVDT,
piezo- electric, strain gauge and variable reluctance type accelerometers – mechanical
type vibration instruments – seismic instrument as an accelerometer and vibrometer –
calibration of vibration pick ups – units of density, specific gravity and viscosity used in
industries – Baume scale API scale – pressure head type densitometer – float type
densitometer – ultrasonic densitometer Bridge type gas densitometer.
3. Pressure measurement (12)
Units of pressure – manometers – different types – elastic type pressure gauges –
Bourde type bellows – diaphragms – Electrical methods – elastic elements with LVDT
and strain gauges – capacitive type pressure gauge – piezo resistive pressure sensor
– resonator pressure sensor – measurement of vacuum – McLeod gauge – thermal
conductivity gauges – Ionization gauge cold cathode and hot cathode types – testing
and calibration of pressure gauges – dead weight tester.
4. Temperature measurement (9)
Definitions and standards – primary and secondary fixed points – calibration of
thermometers different types of filled in system thermometer – sources of errors in
filled in systems and their compensation – Bimetallic thermometers – Electrical
methods of temperature measurement – signal conditioning of industrial RTDs and
their characteristics –3 lead and 4 lead RTDs.
5. Thermocouples and pyrometers (9)
Thermocouples – law of thermocouple – fabrication of industrial thermocouples –
signal conditioning of thermocouple output – thermal block references functions –
commercial circuits for cold junction compensation – response of thermocouple –
special techniques for measuring high temperature using thermocouples – Radiation
methods of temperature measurement – radiation fundamentals – total radiation and
selective radiation pyrometers – optical pyrometer – two colour radiation pyrometer.
