Which of the following is active transducer?
Which of the following is active transducer?
Show Hint
Active transducers generate output directly (e.g., thermocouple).
Updated On: Jul 2, 2026
- Strain Gauge
- Thermistor
- LVDT
- Thermocouple
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Active transducers generate their own electrical output without external power.
Step 1: Strain gauge Requires external power → passive.
Step 2: Thermistor Also requires power → passive.
Step 3: LVDT Needs AC supply → passive.
Step 4: Thermocouple Generates voltage due to temperature difference → active.
Step 5: Conclusion \[ \boxed{\text{Thermocouple}} \]
Final Answer: \[ \boxed{(D)} \]
