El Schreiber SM40<\/strong> es un sensor LVDT inductivo de desplazamiento lineal con electr\u00f3nica integrada<\/strong>, dise\u00f1ado para medir recorridos, movimientos y posiciones en maquinaria industrial, automatizaci\u00f3n, bancos de ensayo y sistemas de control. La familia ofrece carreras nominales de 20, 40, 70, 100, 150 y 200 mm<\/strong> y una carcasa cil\u00edndrica de 25 mm de di\u00e1metro<\/strong> fabricada en acero inoxidable.<\/p>\n

El sensor incorpora un n\u00facleo m\u00f3vil de aleaci\u00f3n n\u00edquel-hierro (Ni-Fe), cuya posici\u00f3n modifica la distribuci\u00f3n de inductancia en las bobinas del transductor. La electr\u00f3nica interna convierte esta variaci\u00f3n en una se\u00f1al proporcional al desplazamiento, disponible en 0\u201320 mA, 4\u201320 mA, 0\u201310 VDC o \u00b110 VDC<\/strong>, seg\u00fan la referencia seleccionada.<\/p>\n

La serie incluye los modelos SM401, SM402, SM403, SM404, SM405, SM406, SM407 y SM408<\/strong>, con salidas crecientes o decrecientes y dos clases de linealidad: 0,5 % y 0,25 %<\/strong>. Su construcci\u00f3n robusta permite seleccionar diferentes configuraciones mec\u00e1nicas, incluidas versiones de n\u00facleo m\u00f3vil, varilla guiada, palpador con muelle, r\u00f3tulas y salida por cable.<\/p>\n

Gracias a su electr\u00f3nica integrada, el Schreiber SM40 puede conectarse a entradas anal\u00f3gicas compatibles de PLC, sistemas de adquisici\u00f3n de datos, indicadores y equipos de control industrial, sin necesidad de acondicionamiento LVDT externo.<\/p>\n

GUEMISA distribuye Schreiber Messtechnik en Espa\u00f1a<\/strong> y asesora en la selecci\u00f3n del transductor de desplazamiento seg\u00fan carrera, se\u00f1al de salida, alimentaci\u00f3n, precisi\u00f3n, montaje y condiciones de la instalaci\u00f3n.<\/p>\n

Una se\u00f1al creciente aumenta cuando la varilla se desplaza hacia el conector del sensor. En los modelos decrecientes se invierte esta relaci\u00f3n.<\/p>\n

Los modelos con salida de corriente y 0\u201310 V utilizan alimentaci\u00f3n de 20\u201332 VDC. Las referencias SM405 y SM406 necesitan alimentaci\u00f3n sim\u00e9trica de \u00b113 a \u00b116 VDC.<\/p>\n<\/details>\n

\n2. Carreras y dimensiones: sensores LVDT de 20 a 200 mm<\/summary>\n

El Schreiber SM40 permite seleccionar seis recorridos de medida est\u00e1ndar. El di\u00e1metro de carcasa es de \u00d825 \u00b10,1 mm<\/strong>. Las dimensiones longitudinales y los pesos var\u00edan con la carrera.<\/p>\n
