EPCOS AG is a TDK Group Company. application notes 1 Applications utilizing the influence of ambient temperature on resistance (self-heating negligible). Temperature measurement The high sensitivity of an NTC thermistor makes it an ideal candidate for temperature sensing ap- plications. These low-cost NTC sensors are normally used for a temperature range of 40 C to +300 C. Selection criteria for NTC thermistors are temperature range resistance range measuring accuracy environment (surrounding medium).
NTC thermistors exhibit a distinctly non-linear R/T characteristic. If a fairly linear curve is required for measurements over a (wide) temperature range, e.g. for a scale, series-connected or paral-leled resistors are quite useful. The temperature range to …
