Abstract
A high-precision and low cost system was built for the electrical characterization of ceramic thermistors at low temperatures, using components readily available in materials research laboratories. The system presented excellent reproducibility in the electrical characterization of NTC ceramic sensors from -75 ºC (195 K) to 23 ºC (296 K). The behavior of the NTC sensor was comparable to that of commercial thermistors only below room temperature (α = -3.2%/K), demonstrating the importance of fully characterizing these materials at both low and high temperatures.
