What are the main differences between active and passive sensors?
What are the main differences between active and passive sensors?
▶ Passive sensors need an external power source to operate. Examples include strain gauges, thermistors, and RTDs (Resistance Temperature Detectors).
▶ Active sensors, however, generate their own power and don't need an external source. A common example is a thermocouple.
Remember, while all sensors are transducers, not all transducers are sensors. Food for thought!
