Analizador de Energía y   Calidad Eléctrica Fluke 437 II

Cotizar

Especialmente diseñado para aplicaciones de transporte

El Analizador de la energía y calidad Eléctrica de la Serie 437 II de Fluke se ha diseñado específicamente para la industria aeronáutica y de defensa. Capaz de realizar mediciones a 400 Hz, el modelo 437 II es indispensable para el trabajo en submarinos, aeronaves y otras aplicaciones de transporte.

Aplicaciones

  • Medición de 400 Hz – capture mediciones de calidad eléctrica en sistemas eléctricos aeronáuticos y militares.
  • Captura de datos PowerWave – capture datos RMS reales para ver todas las formas de onda de modo que pueda determinar cómo interaccionan tensión, corriente y frecuencia.
  • Eficiencia de inversores de potencia – mida tanto la potencia CA y CC, de entrada y salida, para controlar la eficacia de los inversores.
  • Cuantificación monetaria de la energía – calcule el coste fiscal de la energia desperdiciada por una pobre calidad eléctrica.
  • Análisis de la energía– mida el antes y el después para cuantificar las mejoras de la instalación en el consumo de energía, justificando el uso de los dispositivos de ahorro energético.
  • Detección y resolución de problemas en primer nivel de actuación – diagnostique rápidamente los problemas en pantalla, de forma que pueda volver a poner los equipos en marcha.
  • Mantenimiento predictivo – detecte y prevenga los problemas de calidad eléctrica antes de que produzcan tiempos de inactividad de la producción.
  • Análisis a largo plazo – descubra problemas difíciles de detectar o intermitentes.
  • Estudios de carga – compruebe la capacidad de los sistemas eléctricos antes de añadir la carga.
