MEWOI300G Bobine Rogowski portable haute précision Capteur/mètre/sonde de courant à bobine flexible
INTRODUCTION
MEWOI300G Le capteur de courant à bobine flexible (bobine de Rogowski), utilisation de la technologie de bobine Rogowski avancée, est une bobine toroïdale enroulée sur un matériau ferromagnétique non uniforme, aucun effet d'hystérésis, l'erreur de phase est presque nulle et aucune saturation magnétique, haute linéarité. Le signal de sortie est courant sur le différentiel de temps, le signal de tension de sortie en intégrant le courant d'entrée peut être fidèle à, la plage de courant de mesure allant de milliampères à des dizaines de milliers d'ampères. Principalement utilisé pour mesurer le courant de fuite AC, le gros courant AC, les courants harmoniques élevés (jusqu'à 400 fois), le courant de formes d'onde complexes, le courant transitoire d'appel, la phase, l'énergie électrique, la puissance, le facteur de puissance. Avec un intégrateur, facilité d'intégration à d'autres appareils, tels que l'analyseur de détection de phase, les appareils de contrôle industriels, les enregistreurs de données, les oscilloscopes, l'analyseur d'harmoniques, les analyseurs de qualité de l'énergie, enregistreur, systèmes de mesure distribués, systèmes de protection. MEWOI300G Aucun conducteur métallique exposé, mesure sans contact, sûr et fiable ; De petite taille, léger, doux et flexible, adapté aux environnements exigus et aux sites à forte intensité de câbles, et mesurer la taille d'un courant conducteur important ou de forme irrégulière ; Large plage de mesure, haute précision, fiabilité, réponse, bande passante (0,1 Hz-1 MHz) ; La longueur de la bobine peut être personnalisée en fonction des besoins de l'utilisateur. Particulièrement adaptée à la protection de relais, au redresseur contrôlé au silicium, au contrôle de fréquence, aux commutateurs à semi-conducteurs, aux équipements de conversion d'électronique de puissance, au soudage à l'arc et à d'autres environnements industriels. |
