What does a sensor convert into an electrical quantity?
A non-electrical physical phenomenon.
When is a transducer considered a sensor?
When it converts measurable quantities into electrical signals.
What is a measurement chain?
A set of devices or operations used to detect a physical quantity.
What is the role of an analog-to-digital converter in a measurement chain?
It converts the sensor's analog signal for digital signal processing.
Sensor role
Converts physical phenomena into electrical signals.
Transducer function
Converts one energy type into another.
Measurement chain step 1
Detects physical quantity with sensor.
Signal conditioning
Amplifies or filters sensor output.
Passive sensor
Measures phenomena via impedance changes.
Active sensor
Generates electrical energy from physical effect.
Measurement chain sequence
Sense, condition, transmit, convert, process, display.
