Question 1
1. Discuss the working principle of a linear variable differential transformer.
2. An LVDT has the following data: Vin = 6.3 V, Vout =+/- 5.2 v, displacement range = +/-
0.5 in. Calculate the displacement when Vout = +2.6 V.
Question 2
1. Namethe metal combinations of a thermocouple thermometer to measure temperatures
from-270 to 1370 °C:)
2. When the cold junction of a thermocouple thermometer is at 5°C and the hot junctuon at
110 °C, the millivoltmeter shows a deflection of 3.5 mV towards the left. The hot
junction is now put in an unknown temperature while maintaining the cold junction at
5°C. The millivoltmeter now shows a deflection of 4.7 mV towards the left. Calculate the
unknown temperature.
