The man known phenomenon of the long echoes, however, when measurements began, could realize the importance of this approach for industry that gives access to the internal state of the pieces, applying basic principles of physics. For example, when we're on the floor against a mountain and is known to the phenomenon of the echo, we can easily know how far is the wall that reflects sound, and that in doing the exclamation that produces the echo and post the time to hear the echo, if we divide the time in half and take into account the speed of sound in air is about 300 m / sec. We can determine exactly how far is the wall that reflects sound.

Likewise, the ultrasound is a ecopulsante inspection system, which generates a high frequency signal, which is not audible in the range of 1 to 5 MHz and with an oscilloscope, recorded the time it takes the signal traveling in a medium until it is reflected. This medium where sound travels faster, is generally steel in industrial applications and sound travels at speeds in the order of 5.6 km / sec. So by simple calculations can know the thickness of a pipe and quickly determine if you have experienced loss of material due to corrosion.

Although this is the easiest application, which is that sound travels perpendicularly to the surface inspection via longitudinal waves, by coupling half and using the technique of straight beam contact. For other applications, for example to detect fatigue cracks or weld inspection, we have the technical contact and calculations, here the transducer is mounted in a plexiglass wedge with an angle that transmits sound to the room inspected and travels horizontally at a speed of approximately half of longitudinal waves and thus to reflect sound over a discontinuity, by simple trigonometric calculations, we can realize the three-dimensional position of the discontinuities.

Currently the teams are primarily digital form, so to do the calibration, the vast majority of calculations of surface distance, depth and size are performed on automated equipment. The technician who operates the computer compares the pattern detected against a referral is or calibration block and generates the report of the discontinuity or fault is detected.

Here it is important that the reliability of the method is the main function of the technician who operates it as it falls directly on the interpretation of values based on the experience we have.

We have extensively trained technicians with sufficient experience. Our teams are of two types: digital and analog, all laptops and calibrated.
