4.2. Modes of Operation

Try these first

1. 1.

   What does a strain gauge measure?

   Hint

   Think about what happens to materials under stress.

2. 2.

   What type of output does an accelerometer produce?

   Hint

   Consider how data from accelerometers is used.

3. 3.

   What type of sensor uses resistance changes to measure strain?

   • Strain Gauge
   • Thermocouple
   • Accelerometer

   Hint

   Think about materials under stress.

4. 4.

   True or False: A digital sensor provides continuous output data.

   • True
   • False

   Hint

   Remember the nature of data representation.

5. 5.

   Given a new building project, outline the role of both contact and non-contact sensors in ensuring structural integrity.

   Hint

   Think about how data completeness aids in structural assessments.

6. 6.

   Evaluate how sensor durability affects the selection process for a harsh environment monitoring program.

   Hint

   Consider the long-term implications of maintenance costs versus initial sensor choice.
