Sensor Classification and Calibration Quiz

Which of the following is NOT a classification of sensors?

• Active sensors

• Passive sensors

• Dynamic sensors

• Thermal sensors

Active sensors require:

• An external power source

• No external power source

• Only thermal energy

• Magnetic induction

A thermocouple is an example of a:

• Passive sensor

• Active sensor

• Mechanical sensor

• Optical sensor

The output of a passive sensor depends on:

• Input excitation

• Physical property variation

• Amplification process

• Digital processing

Piezoelectric sensors are commonly used for:

• Measuring pressure

• Measuring temperature

• Measuring light intensity

• Measuring displacement

Accuracy refers to:

• Closeness to the true value

• Consistency of measurements

• Smallest measurable value

• Range of measurement

Precision is the:

• Ability to measure a wide range of values

• Repeatability of measurements

• Closeness to the true value

• Sensor's sensitivity to changes

Resolution of a sensor is defined as:

• The ability to detect small changes

• The maximum range of the sensor

• The sensor's response time

• Its output stability over time

Sensitivity in a sensor means:

• Response to environmental conditions

• Change in output for a unit change in input

• The smallest measurable change

• The response time of the sensor

Hysteresis is caused by:

• Non-linear response

• Lagging output during increasing or decreasing input

• Sensitivity to noise

• Inadequate calibration
