Abstract
La invención se refiere a un proceso para la monitorización del grado de desgaste de un sinfín de compresión (8) que transporta un material plastificado, en particular, plástico, contra un elemento que ejerce una resistencia y que está situado en el alojamiento del sinfín (4). A este efecto, la presión del material transportado se mide en dos puntos dispuestos a intervalos a lo largo de la dirección del recorrido. Estos dos puntos están situados a ambos lados de un cuerpo de resistencia (12) hacia el que transporta el sinfín (8). La diferencia entre las dos presiones medidas se utiliza para presentar el grado de desgaste del sinfín (5) y de su alojamiento. El dispositivo para dicho fin tiene una abertura (18) que penetra la pared (20) del alojamiento (4) del sinfín (5) en la zona de su rosca o en la zona inmediatamente contigua a la misma. Una abertura adicional (19) penetra la pared de este alojamiento (4); ambas aberturas (18, 19) están dispuestas axialmente a una distancia entre sí. Un sensor de presión (22, 23) está unido a cada abertura (18, 19)
