A thermistor is inherently suitable for temperature measurement involving

• A. low span and high sensitivity
• B. high span and low sensitivity
• C. low span and low sensitivity
• D. high span and high sensitivity

Answer: (A)

Thermistors are ideal when measuring a single point temperature that is within 50°C of ambient.
If the temperatures are excessively high or low, a thermistor will not work.
Most thermistors work best in the range between -55°C and +114°C.
Sensitivity of thermistor is high.
Span value of thermistor is low.
