Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials.

In the present days we use the measurement of crack by using high cost LVDT having less accuracy.

But here we use less cost ultrasonic sensor for above process. The importance of this paper is that, it is applicable in the detection during both day and night.

Cracks can even spread to interlinking lines and left unchecked, this can lead to a serious accidents. Although most rail line companies spend a great deal of time and money inspecting their rails for potential problems, not all defects can be found using current detection techniques.
