Description

A20220 Transductor DMS | Carcasa de 6 mm compacta

El transductor para puentes completos DMS en carcasa de 6 mm.

  • Uso universal
    para galgas extensiométricas, cajas dinamométricas (presión y fuerza) y otros puentes de medición resistivos
  • Configuración intuitiva
    de los parámetros básicos: sencilla, sin herramientas mediante 4 codificadores giratorios y 8 interruptores DIP
  • Conmutación de zona calibrada
    no se requiere un ajuste complicado
  • Ajuste cómodo
    posibilidad de ajuste directo del punto cero y de la sensibilidad «pulsando un botón» con la función de aprendizaje
  • Separación segura
    según EN 61140 – Protección del personal de mantenimiento y de los dispositivos posteriores contra un alto voltaje inadmisible hasta 300 V CA/CC
  • Alta precisión
    mediante un concepto de conmutación novedoso
  • Consumo mínimo de espacio
    en el armario eléctrico —carcasa instalable en fila de solo 6 mm de ancho— más transductores por metro de perfil DIN
  • Montaje económico
    instalación rápida, conexión cómoda de la energía auxiliar mediante interconector de bus para perfiles DIN
  • 5 años de garantía

La tarea
En las distintas aplicaciones industriales se utilizan galgas extensiométricas con el fin de medir continuamente parámetros mecánicos tales como la fuerza/el peso o la deflexión/torsión. En muchos casos, se utilizan como parámetros de entrada principales para monitorizaciones, desconexiones de seguridad y tareas críticas similares.
Normalmente, se exigen altos niveles de funcionalidad, precisión, flexibilidad y seguridad eléctrica.

Las galgas extensiométricas (DMS) son resistencias altamente sensibles que reaccionan a una carga mecánica con un cambio de resistencia mínimo. Estos cambios pueden registrarse mediante circuitos en puente. El tipo de circuito más común es el puente completo. En los transductores de fuerza y las células de carga, las galgas extensiométricas ya se aplican mecánicamente en una disposición de puente completo. Estos sensores suministran una señal bruta que se procesa y normaliza mediante un transductor DMS.

El problema
Los sensores DMS convencionales tienen valores característicos individuales, en los que hasta ahora el usuario tenía que ajustar su transformador DMS mediante potenciómetros de forma complicada y, a menudo, lenta.

Además, hasta ahora los transductores DMS eran muy anchos en una carcasa instalable en fila y, por tanto, ocupaban mucho espacio en el armario eléctrico. Para el uso a escala mundial, se almacenaban con frecuencia muchas variantes con diferentes tensiones de alimentación.

La solución
Los transductores DMS universales DMS A20220 ofrecen posibilidades de conexión para todos los transductores de fuerza DMS y células de carga DMS convencionales en circuito de puente completo. Mediante los interruptores DIP y los codificadores giratorios, o bien con la «Función de aprendizaje», el usuario puede adaptarlos con flexibilidad a la respectiva tarea de medición. La separación de 3 puertos con separación segura según EN 61140 hasta 300 V CA/CC garantiza la protección del personal y de la instalación, así como una transferencia sin distorsiones de las señales de medición. De este modo, los A20220 ofrecen la máxima eficiencia en espacios muy reducidos. El ajuste del punto cero y de la sensibilidad al sensor DMS individual es particularmente cómodo gracias a la «Función de aprendizaje»: basta con pulsar un botón situado en la parte frontal de la carcasa. En el caso de los sensores cuyos valores característicos conoce el usuario, la calibración puede realizarse muy fácilmente mediante cuatro codificadores giratorios y ocho interruptores DIP.

Las tareas de medición especiales pueden resolverse con dispositivos que Knick parametriza según las especificaciones individuales. Los dispositivos fijos sin interruptores se utilizan, por ejemplo, cuando se debe excluir una manipulación o confusión.
