Basic components in a measurement system
Basic components in a measurement system are shown below:
It is also important to mention that a power supply is an
important element for the entire system.

Amplification and Conditioning
Major issues in instrumentation and measurement systems
? Sensitivity (deflection over the change in the variable)
? Accuracy (uncertainties)
? Resolution (the smallest step that can be distinguished)
? Robustness (noise, disturbance, or drift)
? Response time (fast response/high bandwidth)
