The Correct Option is D
Solution and Explanation
P: Rotary Variable Differential Transformer (RVDT)
The RVDT is most commonly used for measuring angular displacement. Therefore, P is matched with III.
Q: Thermocouple
A thermocouple is a sensor used to measure temperature, as it produces a voltage proportional to the temperature difference. Therefore, Q is matched with IV.
R: Ionization Gauge
The ionization gauge is a sensor used for measuring vacuum, as it measures the ionization of gas particles within a vacuum. Therefore, R is matched with I.
S: Strain Gauge
A strain gauge is commonly used to measure force or strain in an object. Therefore, S is matched with II.
Thus, the correct matches are:
P – III (Angular displacement measurement)
Q – IV (Temperature measurement)
R – I (Vacuum measurement)
S – II (Force measurement)
Therefore, the correct answer is (D).

Top Questions on Measurements
- A metallic strain-gauge (SG) with resistance \( R_{SG} \) is connected as shown in the figure, where \( R_{L1} \), \( R_{L2} \), \( R_{L3} \) represent the lead wire resistances. The SG has a gauge factor of 2 and nominal resistance \( R_N \) of \( 125 \, \Omega \). When the SG is subjected to a tensile strain of \( 2 \times 10^{-3} \), the resulting change in \( R_{SG} \) is \( \Delta R \). The \( \Delta R \) value is measured as \( \Delta R_{MEAS} = R_{EQ2} - R_{EQ1} \). The \( R_{EQ1} \) and \( R_{EQ2} \) are the equivalent resistances measured between the terminals 1 and 2, and terminals 2 and 3, respectively.
If \( R_{L1} = R_{L2} = 5 \, \Omega \), and \( R_{L3} = 4.95 \, \Omega \), the measured value of tensile strain is ________ \( \times 10^{-3} \) (rounded off to two decimal places). - Power consumed by a three-phase balanced load is measured using two-wattmeter method.

In a single-phase AC circuit, the power consumed by load resistance $R_L$ for an excitation $V_S$ is measured by a wattmeter. The same wattmeter is connected in two different topologies, Topology-A and Topology-B, as shown in the figure. Different branch currents and voltage drops are also marked in the figure. Among the following options, the condition that ensures low error in the wattmeter reading for both the topologies is
