GL840-WV
El Graphtec GL840WV es un registrador de datos de alta calidad de 20 canales que se puede expandir hasta 200 canales en total. Cada canal está aislado. Esta unidad es adecuada para muchas aplicaciones, incluida la medición de temperatura con múltiples canales. La pantalla a color integrada de 7 pulgadas proporciona una experiencia de visualización de datos intuitiva. Aunque este sistema está diseñado como una unidad independiente, se puede conectar a una PC si es necesario.
El GL840WV está diseñado para aplicaciones que requieren pruebas de medición de alta prescisión y alto voltaje. Si bien el rango de voltaje de entrada es el mismo en GL840M y GL840WV (20 mV a 100V), el voltaje máximo sostenido de hasta 1 minuto es mayor. El GL840WV puede soportar hasta 300Vp-p en lugar de los 60Vp-p del GL840M. La precisión también es más precisa en el GL840WV en un 0,05%.
El GL840WV ha sido diseñado con un sistema de entrada extremadamente aislado que garantiza que todas las señales no se vean afectadas por el ruido del canal exterior. Con esta capacidad, este sistema se puede utilizar para una variedad de aplicaciones que incluyen voltaje, humedad, temperatura, pulso y lógica.
El GL840WV viene de serie con 20 canales de entrada analógica, pero se puede expandir fácilmente hasta 200 canales al agregar la base de terminal de extensión de 20 canales opcional (B-566) y otras unidades de terminal de entrada (B-564 o B-565)
