El Schreiber SM44<\/strong> es un sensor LVDT inductivo de desplazamiento lineal con electr\u00f3nica integrada<\/strong>, disponible para recorridos nominales de 100 y 200 mm<\/strong>. Su carcasa cuadrada de 30 \u00d7 30 mm<\/strong> facilita la integraci\u00f3n en maquinaria industrial, mecanismos lineales, sistemas de automatizaci\u00f3n y bancos de ensayo.Fabricado en Alemania por Schreiber Messtechnik<\/strong>, transforma el movimiento axial de un n\u00facleo de aleaci\u00f3n Ni-Fe en una se\u00f1al el\u00e9ctrica proporcional al desplazamiento. La gama incluye ocho modelos, SM441, SM442, SM443, SM444, SM445, SM446, SM447 y SM448<\/strong>, con salidas de 0\u201320 mA, 4\u201320 mA, 0\u201310 VDC o \u00b110 VDC<\/strong>, seg\u00fan la referencia seleccionada.La electr\u00f3nica de acondicionamiento est\u00e1 incorporada en el sensor, lo que permite conectar su salida directamente a entradas anal\u00f3gicas compatibles de PLC, indicadores y sistemas de adquisici\u00f3n de datos. El SM44 dispone de linealidad del 0,5 % o 0,25 %<\/strong>, frecuencia l\u00edmite de 800 Hz<\/strong> y protecci\u00f3n IP67 con el conector complementario correctamente instalado<\/strong>.<\/p>\n

La construcci\u00f3n cuadrada ofrece una alternativa a los transductores LVDT cil\u00edndricos cuando se necesita una fijaci\u00f3n sobre superficies planas o una geometr\u00eda de montaje espec\u00edfica. Existen versiones con varilla guiada, r\u00f3tulas de articulaci\u00f3n y salida mediante cable. La documentaci\u00f3n espa\u00f1ola tambi\u00e9n recoge una ejecuci\u00f3n con palpador y muelle de retorno para 100 mm.<\/p>\n

GUEMISA distribuye los sensores LVDT Schreiber en Espa\u00f1a<\/strong> y ofrece asesoramiento t\u00e9cnico para seleccionar el recorrido, la se\u00f1al de salida, la alimentaci\u00f3n y la configuraci\u00f3n mec\u00e1nica, tanto para nuevas instalaciones como para sustituciones de transductores de posici\u00f3n industriales.<\/p>\n

La serie SM44 ofrece ocho versiones el\u00e9ctricas. La elecci\u00f3n determina la se\u00f1al de salida, su sentido de variaci\u00f3n y la tensi\u00f3n de alimentaci\u00f3n necesaria.<\/p>\n

Se\u00f1al creciente<\/strong> significa que la salida aumenta cuando la varilla se desplaza hacia el conector del sensor. Una se\u00f1al decreciente presenta el comportamiento contrario.<\/p>\n

Las versiones SM445 y SM446 requieren alimentaci\u00f3n sim\u00e9trica. Para conectar el equipo a un PLC deben comprobarse tanto la entrada anal\u00f3gica como la alimentaci\u00f3n disponible.<\/p>\n<\/details>\n
