El transductor inductivo Schreiber SM46 es un amplified LVDT sensor de ejecución «druckdicht» (estanca al fluido), mecanizado en un bloque macizo de acero inoxidable. Presión hidráulica estática admisible: 315 bar. Se rosca directamente en cámaras de cilindros oleohidráulicos, válvulas proporcionales marinas y cabos de extrusión petroquímica.
La electrónica activa se aloja en el cabezal superior (Ø 30 mm). Carrera útil del núcleo, en aceite: 20 mm. Salida: 4-20 mA o 0-10 V. Montaje según DIN 6149 (rosca de inserción M18x1.5 y junta tórica NBR 90). Resistencia a choques: 250 g. Aplicación de estos linear position sensors: embebidos en maquinaria pesada. Acoplamiento y versiones modulares: Technical consultation.
Frequently Asked Technical Questions
- Are the stem and core of the SM46 permanently exposed to pressurized hydraulic fluid?
Sí. El vástago inoxidable y el núcleo magnético de NiFe se sumergen en el fluido presurizado del cilindro. El tubo de bobina soporta hasta 315 bar e impide que el aceite llegue al cabezal de la electrónica. - ¿Qué rosca y junta utiliza el SM46 para el sellado a 315 bares?
Rosca de inserción de paso métrico fino M18x1.5 con junta tórica NBR 90, según DIN 6149-2 y 3.
