Classification Of Sensors And Transducers Flashcards
What is an input transducer
A device that converts energy from one form to another
What is a sensor
A device used to detect a signal
What is signal conditioning
It modifies output of transducer
What is an output transducer
It converts output to a convenient form
What is excitation
Supplies signal or power to operate the other components
What are the 6 main forms of energy and their associated signals relevant to measurement
Mechanical- displacement, velocity, acceleration, force, flow.
Radiant- visible, NIR radiation
Thermal- temperature, heat flow.
Electrical- voltage, current, resistance.
Magnetic- magnetic field , magnetic flux.
Chemical- chemical composition, ph
What is a self generator transducer
It converts one form of energy to another (usually electrical), without requiring additional supply of energy
What is a modulator transducer
It requires and extra source of energy and modulate it’s flow
What is a modifier transducer
It modifies the form of the signal but not the energy
