Long-term relative stability of thermistors

Optimization and temperature mapping of an ultra-high thermal stability environmental enclosure

“…The corrections were all very smallwithin ±1.1 mC -indicating that the manufacturer had done a good calibration job at the factory. The self-heating effect of thermistors may potentially cause incorrect measurements when thermistors traverse regions of changing wind velocity (1-2 m/s) [12,13]. The excitation current of the Instrulab 3312A is about 80 A which generates a heat pulse of 3.5 J in each thermistor during the 0.3-s measurement.…”

A review on various temperature-indication methods for Li-ion batteries

“…In addition, a four-terminal contact is not required since thermistors have a high resistivity, which saves cable space and cost. Although thermistors had a reputation of being unstable, the stability improved over the years by adopting new techniques, reaching good long-term stability [183][184][185][186][187]. Using specific provisions with the measurement instrumentation, errors of <1 mK can be reached [188], although the accuracy in commercial applications often results in the order of ±1 o C [44].…”

Evaluating Suitability of a DS18B20 Temperature Sensor for Use in an Accurate Air Temperature Distribution Measurement Network

“…The accuracy of temperature sensors after manufacture is specified by their vendors; variation might range from as low as ±0.25 °C up to ±2 °C [4]. A study on thermistors found that their accuracy deteriorated very little over time [5], and this should hold for both RTDs and integrated circuit temperature sensors that have been manufactured from materials of high purity. However, making room temperature measurements that are accurate to 1°C could be complicated by the fact that the same thermometer, placed at different heights in the same room, could report temperature differences well in excess of the above-mentioned amount of 1 °C [6].…”
