Abstract

MONTAJE TERMICAMENTE AUTOAJUSTABLE PARA UN SENSOR DE PROXIMIDAD (48) PARA DETECTAR EL MOVIMIENTO DE UNA PUNTA (30) DE ALABE DE TURBINA DENTRO DE UN ALOJAMIENTO DE TURBINA, UN SENSOR (48) DE PUNTA DE ALABE ESTA SOSTENIDO DE MODO QUE SE MUEVA APROXIMANDOSE Y ALEJANDOSE DEL CAMINO DE DESPLAZAMIENTO (30A) DE LA PUNTA DE ALABE. UN ELEMENTO TERMICAMENTE EXPANSIVO (20) ESTA ACOPLADO OPERATIVAMENTE AL SENSOR (48) PARA MOVER A ESTE ULTIMO EN LA CAMARA HACIA EL CAMINO DE DESPLAZAMIENTO (30A) AL CALENTARSE DICHO SENSOR. HAY DISPUESTO UN RESORTE (22) PARA MANTENER EL SENSOR EN CONTACTO CON EL ELEMENTO TERMICAMENTE EXPANSIVO (20) DURANTE TANTO LA EXPANSION COMO LA CONTRACCION DE ESTE.
