Sensors and Transducers

There are two types of encoder explained in the video which are

• Quadratic and linear encoders

• Linear and absolute encoders

• Resistive and inductance encoders

• Rotary and resistive encoders

Both linear encoder and rotary encoder can be based on absolute or incremental measurement type

• True

• False

Rotary encoder is also know as

• Linear encoder

• Absolute encoder

• Shaft encoder

• Binary encoder

The shown image represent the

• Incremental linear encoder

• Absolute linear encoder

• Incremental rotary encoder

• Absolute rotary encoder

The shown image represent the

• Incremental linear encoder

• Absolute linear encoder

• Incremental rotary encoder

• Absolute rotary encoder

The shown image represent the

• Incremental linear encoder

• Absolute linear encoder

• Incremental rotary encoder

• Absolute rotary encoder

Absolute rotary encoder can be used to measure

• distance

• linear speed

• angular position

• linear position

The incremental rotary encoder can be used to measure the following physical parameters except

• distance

• linear speed

• angular position

• linear position

Single turn absolute rotary encoder can be used for long distance measurement

• True

• False

In case of losing power supply, incremental rotary encoder has advantage compared to absolute rotary encoder in preserving the previous measurement

• True

• False
