Transcribed Image Text:

Capacitive sensors are based on the concept of a parallel plate capacitor. Considering capacitance of such a sensor, what are the 3 parameters that these sensors can take advantage of? (b) (4%) Optical fiber sensors are based on modulation of light by the parameter of interest. They can be either extrinsic or intrinsic. Explain how the two approaches are different. (c) (4%) What are the LVDT sensors and how can they be used to measure displacement? (d) (3%) How does a piezoelectric sensor differ from a piezoresistive sensor? (e) (4%) State at least two key differences between the thermocouple and the thermistor temperature sensors. (f) (4%) What is the difference between a strain gage and a piezoresistor?
