Practical Control - Angular Displacement Flashcards
1
Q
Capacitive Transducer key points?
A
Parallel plate capacitor depends on the overlap area of the two plates and so a change in area produces a change in capacitance.
2
Q
Optical Shaft Encoder Produce what kind of displacement?
A
Digital
3
Q
The two types of optical shaft encoders are?
A
Incremental and absolute
4
Q
Incremental use ** spaced ** to measure angular displacement through phase difference?
A
Evenly. slits
5
Q
Absolute encoders output a signal in two forms, what are these?
A
Binary and Coded
6
Q
What is the one error with binary absolute encoders? What was invented to fix this?
A
If more than one window in the 0000 slits changes the system fails. Gray Code was made.
7
Q
Optical sensors use a light source and **
A
A detector
