Abstract
A systematic method is developed to select the most appropriate sensor
for a particular application. A wide range of candidate sensors exist,
and many are based on coupled electrical and mechanical phenomena,
such as the piezoelectric, magnetostrictive and the pyro-electric
effects. Performance charts for sensors are constructed from suppliers
data for commercially available devices. The selection of an appropriate
sensor is based on matching the operating characteristics of sensors
to the requirements of an application. The final selection is aided
by additional considerations such as cost, and impedance matching.
Case studies illustrate the selection procedure.
