Overview
ABSTRACT
This article reviews the most common criteria that govern the choice of a measurement chain which is strongly influenced by the number of constraints imposed by the environment used. The magnitude of the temperatures to be measured has considerable influence on the sensor choice and the interval explored around the average value enables precision choice of the measurement chain. The needs in terms of technical characteristics (sensitivity, reliability, accuracy, etc.) then define the sensor characteristics. The response nonetheless remains a compromise, the relevance of which can only be assessed by the experimenter.

INTRODUCTION
This summary article is an introduction to the Thermometry section, and as such, frequent references will be made to the various articles in this section, where the specific methods for each sensor are detailed.
In this article, the sensors and methods of use will be briefly described, with reference to the specialist articles in this Measurement & Control treatise.
The complexity of choosing a measurement chain is obviously linked to the number of constraints imposed by the environment in which it will be used. The nature of the information required and the measurement method will also be important selection criteria. Each individual case will have its own answer, and it is not possible to consider all cases here. Many selection criteria may seem incongruous at first glance, such as sensor weight, color, etc., but in some cases they may be of importance. We'll try here to review the most common criteria in response to the questions posed above. The answer will often be a compromise whose relevance can only be judged by the experimenter.
