Kelvin double bridge: It is a standard testing instrument for accurate measurement of very low resistances such as shunts, copper & aluminum conductors or wire and specific resistance determinations of heavy distribution transformers. The bridge comprises 10 steps of standard resistance of X 0.01 ohms and a circular slide wire having total resistance of 0.01 ohm & divided into 500 equal parts so that each division correspond to 0.00002 ohm (or 20 micro-ohm). 4, record 1, English, - Kelvin%20double%20bridge

In thermal conductivity analysers, a Wheatstone Bridge Circuit measures the imbalance caused by passing gas over detector filaments, using half of the cells for the fumigant air mixture and the other half for air as a control. This analyser, in a portable form, is commonly used to check for methyl bromide in ship holds, but it can also be calibrated for other gases. It will not differentiate between fumigants if mixtures are used. 1, record 3, English, - thermal%20conductivity%20analyser

Dans ce genre d'appareil, on utilise un circuit à pont de Wheatstone pour mesurer le déséquilibre provoqué par le passage d'un gaz au-dessus des filaments détecteurs. La moitié des cellules sert à l'analyse du mélange fumigant/air; l'autre moitié sert aux mesures témoins avec de l'air uniquement. On utilise couramment des modèles portatifs pour mesurer les concentrations de bromure de méthyle dans les cales de navire, mais on peut aussi étalonner les analyseurs en fonction d'autres gaz. En pratique, les analyseurs à conductivité thermique conviennent mal pour l'analyse de mélanges de fumigants. 1, record 3, French, - analyseur%20de%20gaz%20%C3%A0%20conductivit%C3%A9%20thermique

Dans le comparateur électronique, l'extrémité du palpeur opposée à celle qui ausculte la pièce à mesurer se déplace à l'intérieur d'une paire de bobines. La variation du couplage entre les bobines engendrée par le déplacement de ce noyau est amplifiée et entraîne les déviations d'une aiguille de galvanomètre sur un cadran gradué. 1, record 4, French, - comparateur%20%C3%A9lectronique
