Hi i am santanu das,a studennt of persuing b-tech,my mail id is [email protected] and i want a book about this-(Definition, principles of sensing and transduction, classification
Mechanical and Electromechanical sensors
Resistive (potentiometric) type: Forms, materials, resolution, accuracy,
sensitivity
Strain Gauges: theory, types, materials, design consideration, sensitivity,
gauge factor, variation with temperature, adhesives, rosettes, applicationsforce,
velocity and torque measurements
Inductive sensors: common types- reluctance change type, mutual
inductance change type, transformer action type, - brief discussion with
respect to materials, construction and input output variables,
Ferromagnetic plunger type-short analysis; proximity measurement
LVDT: Construction, materials, output-input relationship, I/O curve,
discussion,Capacitive sensors: Variable distance- parallel plate type, Variable area- parallel plate,
serrated plate/teeth type and cylindrical type, variable dielectric constant type:
calculation of sensitivities; proximity measurement
Stretched Diaphragm type: microphones, response characteristics
Piezoelectric elements: piezoelectric effects, charge and voltage coefficients, crystal
model, materials, natural and synthetic types their comparison, force and stress
sensing, piezoelectric accelerometer
Tachometers Stroboscopes, Encoders, seismic accelerometer, Measurement of
vibration.
Module II
