1. Thermometry using temperature microprobes

Standard thermocouples meet the most common requirements of the industrial environment. In addition to the metrological qualities for which they were designed, they must also satisfy robustness and stability criteria which are generally opposed to those increasingly sought after: speed, resolution and discretion.

Inexpensive and easy to implement, thermoelectric couples are in some cases the only means of measuring temperature on a smaller dimensional scale than other techniques. The same applies to so-called non-intrusive techniques, generally optical, which are limited by numerous drawbacks (optical characteristics of the medium and object under test, topography and extent of the measurement field, temperature levels, complexity, price, etc.).
