Concept explainers
A thermocouple can measure higher temperatures than a thermistor.
To identify: If the given statement is True or False.
Answer to Problem 1TFQ
The given statement is True.
Explanation of Solution
Thermocouple is a device formed by joining two “dissimilar metals”. The basic principle is to apply heat to metals and a small “voltage” of the order of 100 mV or less is produced across their junction called See beck voltage. This is directly proportional to the temperature.They are basically used in industries since they have a wider temperature range and hence can measure very high temperatures.
But, a thermistor which works based on resistance-temperature relation;respond over a very narrow range of temperature of about
Thus, the given statement is correct.
