9 Questions
What is the unit of measurement for accelerometers?
Meters per second squared (m/s2)
Which type of sensor is used to measure the rotational speed of an object?
Tachometer
Which type of tachometer can perform statistical functions and store readings?
Digital tachometer
What is the function of a piezoresistive accelerometer?
Change resistivity in response to stress
What is the primary role of encoders in motion devices?
Report the physical position of an object
In relation to motion devices, what does 'accuracy' refer to?
The maximum deviation between desired and actual position
Which sensor can convert rotary or linear displacement to resistance?
Potentiometer
What is the key difference between contact and non-contact tachometers?
Contact type tachometers require physical contact with the object being measured, non-contact do not.
What is the role of resolvers in motion devices?
Report the physical position of an object
Test your knowledge on motion devices and sensors used for reporting the physical position of objects. Explore the functions of potentiometers, accelerometers, tachometers, resolvers, encoders, and how they provide feedback on displacement, position, speed, and acceleration. Learn about motion transducers and their analog or digital output signals.
