Thermocouple

RTD

thermistor

Noise can induce errors in them

They have small sensitivity

All answers are correct

They always generate mVolts

whole operating range is needed

high sensitivity is required

strong electromagnetic and radio frequency interference exist.

all answers are correct

that it has a long response time

that it takes a long time delay  for temperature reading

All answers are correct

that heat has to go through the thermo well before reaching the temperature sensor.

 the thermocouple junction and the thermocouple leads are at the same temperature.

The thermocouple wires and the voltmeter leads are not of the same metal type

 there is an electromagnetic interference around the thermocouple  

used to measure extremely low temperatures

all answers are correct

a series of thermocouples connected in series to provide a high voltage output reading

Eliminate the effect of the junction created by measurement leads wires and the thermocouple wires.

All answers are correct

Eliminate the voltage created by the reference junction

wire length

Wire size

All answers are correct

Metals they are made of.
