Model PH200 je digitalni ultrazvučni mjerač debljine. Based on the ultrasonic principle , the instrument is capable of measuring the thickness of various materials, such as metal, plastics, ceramic, glass and many other good ultrasonic conductors. Također može mjeriti brzinu svih vrsta materijala. Compared with the traditional measurement methods, the advantages of ultrasonic thickness gauge is exposed to one side of the workpiece to complete the measurement. Its unique non-destructive testing performance provide the perfect solution for the thickness testing of closed pipes, containers, etc. It is widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields because of monitoring corrosion thinning degree of various pipes and pressure vessels.It can also be used for precise measurement of sheet metal and machined parts .

Princip rada

The digital ultrasonic thickness gauge determines the thickness of a part or structure by accurately measuring the time required for a short ultrasonic pulse generated by a transducer to travel through the thickness of the material, reflect from the back or inside surface, and be returned to the transducer. The measured two-way transit time is divided by two to account for the down-and-back travel path, and then multiplied by the velocity of sound in the material. Rezultat je izražen u dobro poznatom odnosu.

  

gdje :

H － debljina ispitnog komada.

v － Brzina zvuka u materijalu.

t － Izmjereno povratno tranzitno vrijeme.

 

To make sure the probe working properly, it needs to use couplant to isolate the air between the probe surface and the measured workpiece surface. Tekućina koja se koristi za spajanje između sonde i obratka naziva se spojnica.
