PYQs Based Test - 08 : Sensors and Industrial Instrumentation

The most suitable pressure gauge to measure pressure in the range of 10⁻⁴ to 10⁻³ torr is

Thermocouples measure temperature based on

A thermocouple is suddenly immersed in a medium of high temperature. The approximate time taken by the thermocouple to reach 98% of the steady-state value is

Liquid flow rate is measured using

Four identical resistive strain gauges with gauge factor of 2.0 are used in a Wheatstone bridge as shown in the figure below. Only one of the strain gauges R${}_{SENSE}$ changes its resistance due to strain. If the output voltage V${}_{OUT}$ is measured to be 1 mV, the magnitude of strain, in units of microstrain, is
