SENSORES DE MEDIDA LINEAL ELTRA
Los transductores lineales se utilizan para medir desplazamientos en línea recta.
Los potenciómetros están constituidos por un alambre o una capa de metal, enrollado en un soporte aislante, y un contacto móvil capaz de desplazarse a lo largo del conductor. El principio de funcionamiento se basa en la variación de la resistencia dentro de un circuito eléctrico, determinado por el desplazamiento del objeto para el cual se quiere medir la posición.
Eltra ofrece versiones de potenciómetros de varilla o cursor, disponibles con diferentes
tipos de montaje (con estribos, bridas de sujeción y juntas a rótula) y varios niveles de protección IP, con el fin de satisfacer al mayor número de requisitos dictados por el sector de empleo.
