Electrical micro cuts and resistance monitoring bench
As part of multi-physics tests, the 6NAPSE Group has acquired a test bench to monitor the loss of electrical contact and drift in contact resistance.
Solve the problems of electrical micro cuts.
Electrical micro cuts
Electrical contacts are often present in electromechanical devices. They allow current to flow between two mechanically separable elements. As a system with electrical contact we can talk about connectors, relays, switches, circuit breakers, transmission lines…
However, the quality of these electrical contacts is not always perfect, several factors can affect their proper functioning: thermal stress, mechanical stress (vibration), current level, condition of the contact surface…
A faulty electrical contact manifests itself with electrical outages (remarkable without a device due to the time scale) or electrical micro-outages (detectable with specific devices) during the operation of the electromechanical system.
The 6NAPSE Group fits into your electronic reliability projects.

Caractéristiques techniques
Le banc de détection de microcoupures et de suivi de résistance est conçu pour tester l’interruption d’un contact et la variation de sa résistance en même temps. Les fonctions nécessaires du module pour tester un contact sont :
- Une source linéaire rapide et précise qui fournit :
- Le courant constant nécessaire pour le contact à tester ;
- Une tension constante imposée lorsque le contact est ouvert ;
- Un comparateur rapide de suivi d’un circuit logique synchrone permettant :
- Le contrôle d’une largeur de pulse minimale afin de rejeter les pulses très courts ;
- Le comptage des pulses ;
- La mesure de la durée des pulses
- Un low amplifier qui fournit une mesure précise DC de la résistance de contact
