Amplified LVDT | Range 80 to 360 mm | Stainless Steel Housing Ø 25 mm | IP66 | Outputs 4-20mA / ±10V | Clamp Mounting

El transductor inductivo Schreiber SM42 es un amplified LVDT sensor para desplazamientos largos. A diferencia de los LVDT de transformador diferencial, la lectura se basa en la distribución de inductancia parcial de bobina («Partiellen Induktivitätsverteilung»). Su electrónica integrada procesa de forma analógica rangos mecánicos desde 80 mm hasta 360 mm útiles (80, 170, 240 y 360 mm), en una carcasa de acero inoxidable de 25 mm de diámetro.

Aplicaciones: compuertas hidráulicas, cilindros de laminación y expansiones térmicas de tuberías. Salidas: corriente (4-20 mA) o tensión doble (±10 V). Alimentación: 20-32 V DC para lazos de corriente y ±13-16 V DC para salida de tensión. Linealidad: < 0,5 % y < 0,25 % en la selección opcional. Resistencia a choques: 250 g SRS. Ancho de banda: 800 Hz. Protección: IP66 con conector roscado BI423. Este linear position sensor tiene variantes con protección en Kynar y rótulas M5 integradas: Technical consultation.

Frequently Asked Technical Questions

  • What advantage does the SM42's "partial inductance" principle offer compared to a standard SM40 Series sensor?
    El principio de inductancia parcial permite leer carreras físicas de hasta 360 mm con una linealidad de 0.25 % en la selección de mayor precisión.
  • ¿Hay versiones con vástago guiado o rótulas?
    Sí. La versión «.F» lleva el vástago guiado por un casquillo de latón. Las versiones «.G» y «.H» incluyen rótulas esféricas para absorber el desalineamiento angular.
