Does the output change proportionally to the input?
What is the smallest increment the system can detect?
To be processed by computers or microcontrollers, the continuous electrical signal is sliced into discrete digital values. 3. Key Performance Indicators Messelektronik und Sensoren: Grundlagen der Mes...
How much does the output change when the input changes slightly?
At the heart of every measurement is a . Its job is to detect a physical quantity—such as temperature, pressure, or light—and convert it into a measurable electrical signal (voltage, current, or frequency). 2. The Chain of Measurement Does the output change proportionally to the input
To evaluate a sensor system, engineers look at specific "Quality Factors":
Does the sensor give the same reading when approaching a value from above versus below? 4. Modern Trends: Smart Sensors Its job is to detect a physical quantity—such
Raw signals are often too weak or noisy. Measurement electronics amplify, filter, and linearize these signals to make them usable.
