12 Questions
What is the relationship between the measured voltage and RTD resistance in a two-wire design?
Non-linear
What is a key characteristic of thermistors?
Resistance change with temperature
How are Positive Temperature Coefficient (PTC) thermistors different from Negative Temperature Coefficient (NTC) thermistors?
PTC made from oxides of metals, NTC made from semiconductors.
What is the range of temperature that can be measured by a typical thermistor?
-40 to +150 °C
What is the main reason for the use of four-wire designs in resistance measurements?
