What is correct about the following statements?

RTD thermometer has the largest input range

Thermistor thermometer has linear relationship between temperature and resistance.

Thermistor thermometer has highest sensitivity

Thermocouple thermometer has highest sensitivity

Solution

Answer:

Thermistor thermometer has highest sensitivity

Explanation:

Thermistor is a temperature sensitive device. If the temperature varies, then the resistance of the thermistor either increases or decreases. By using this property, we can use it as a temperature sensor. Thermistor Thermometer is a resistor type thermometer. Thermistor thermometers have high sensitivity but it has nonlinear characteristics.
