Abstract

Detector por ultrasonidos, de carril roto, deteriorado o deformado geométricamente, que consiste en la fijación por medios convencionales sobre los carriles (1) en la base o en el alma de los mismos de transductores (2) con independencia de que estos sean piezoeléctricos, magnetoestrictivos o similares, pudiendo incorporarse en ambos carriles en escucha directa o de forma independiente, o bien opcionalmente combinados con ecometría en el transmisor/receptor situándose en el mismo punto en ambos carriles o en carriles diferentes.Ultrasonic detector, of broken lane, deteriorated or geometrically deformed, which consists in fixing by means of conventional means on the rails (1) in the base or in the core thereof of transducers (2) regardless of whether they are piezoelectric, magnetostrictive or similar, being able to be incorporated in both lanes in direct or independent listening, or optionally combined with ecometry in the transmitter / receiver being located in the same point in both lanes or in different lanes.
