ZTB400P

Resonators

The ZTB400P is a high power magnetostrictive transducer designed to resonate at 4 kHz in 0 - 80 Hz range along with a minimum load of 1.5 kN. This vibration transducer finds its application in generating vibration waves to test the integrity of components such as bridges, transmission lines and other large structures.

Application Field

The ZTB400P is mainly used for large structure investigation, such as bridge during construction and existing bridges. The vibrational amplitude and frequency of the unit provide a valuable snapshot of the structure’s integrity, providing a quantitative evaluation to the severity of any potential structural issues.

The ZTB400P is also a highly effective tool for the investigation of steel transmission lines, for example. The unit can typically accommodate large steel structures and its ability to produce a wide spectrum of frequencies makes it ideal for such testing.

Working Principle

The ZTB400P works by converting an electrical signal into a mechanical oscillation. This process is known as magnetostriction, and it involves passing an electric current through a metal coil to create an electromagnetic field. This in turn causes the metal coil to expand or contract, generating an oscillating force.

The frequency of the oscillation is determined by the magnetostrictive material used to create the electromagnetic field. In the case of the ZTB400P, the frequency of the vibration is determined by the particular material used in the coil. The higher the frequency, the higher the power output.

The vibration created by the transducer is transmitted through the structure being tested. By observing the amplitude and frequency of the vibrations, engineers can determine the condition of the structure.

The ZTB400P is a versatile, high-power transducer that can be used for a variety of applications. Its ability to produce a wide spectrum of frequencies makes it an ideal tool for testing the integrity of bridges, transmission lines and other large structures.
