The platinum resistance thermometer is a versatile instrument for temperature measurement in the range from — 200° to 1000°C. Nous allons essayer de comprendre comment une telle échelle de température peut être mise en place. Lors de l'étalonnage, le thermomètre calibré sous test et la sonde étalon sont soumis à la même température dans une unité de régulation de température.. Dès qu'une température stable est atteinte, les instruments sous test sont lus ou les signaux de sorties sont mesurés (résistance, tension thermoélectrique, signal standard) et comparés avec la sonde de référence. Thermometer designs for pipes will simply be fixed with a worm drive hose clip. la thermistance, communément appelé thermomètre à résistance ou RTD (De 'Anglais Résistance Temperature réetector), Il est capteur de température qui exploite la variation de résistivité de certains matériaux à changement de température.
