Transducer arrangement for ultrasonic rail tester coupling carriages

摘要: A transducer arrangement for ultrasonic rail tester coupling carriages comprising a first pair of flat angle signal transducers that are both connected to be senders and receivers directed in opposite directions lengthwise forwardly rearwardly the along center head, second directly but canted toward gauge edge at an 19°, third transducers, one which is sender other receiver, 80 degrees provide zig-zag path multiple bounces across head. The act through transmitting wedges made material inefficient as medium sound may sent such significantly improved noise ratio results.
