Question:
Which of the following is a temperature measurement element?
Which of the following is a temperature measurement element?
Show Hint
Thermocouples convert temperature difference into voltage.
Updated On: Jul 2, 2026
- Thermocouple
- Pressure gauge
- Flow meter
- Tachometer
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Different instruments measure different physical quantities.
Step 1: Thermocouple Used to measure temperature based on Seebeck effect.
Step 2: Pressure gauge Measures pressure.
Step 3: Flow meter Measures flow rate of fluids.
Step 4: Tachometer Measures rotational speed.
Step 5: Conclusion Only thermocouple measures temperature. \[ \boxed{\text{Thermocouple}} \]
Final Answer: \[ \boxed{(A)} \]
