Eddy Current Tube Testing Equipment

This induces a flow of eddy currents around the test material or in the case of a sector coil in the area under the coil.

Eddy current tube testing equipment.

Ect began largely as a result of the english scientist michael faraday s discovery of electromagnetic induction in 1831. Zetec is the industry leader for cost effective eddy current testing ect in complex applications. Tube testing technologies products selectedtext inspection instruments prod name. Eddy current tube testing.

The first commercial use of this type of testing was introduced in 1930 and was called the model e probolog. Eddy currents were first observed by françois arago in 1824 but french physicist léon foucault is credited with discovering them in 1855. The theory was first introduced in 1879. Encircling and sector eddy current coil tests perform in this manner.

Two coupling paths exist between the transmitters and receivers. The indirect coupling path originates in the transmitter s magnetic field that diffuses radially outward through the wall. Get eddy current equipment for tube bar and wire from bkn leading ect testing equipment manufacturer. Applicable to surface defect detection of non ferrous metals stainless steel tubes they can be widely used for on line or off line non destructive testing of raw materials for various industry.

Eddy current testing equipment utilizes the frequency generator impedance bridge as well as a probe that houses one or more coils. High quality eddy current testing solutions for complete inspections. The direct path inside the tube is rapidly attenuated by circumferential eddy currents induced in the tube s wall. The product is passed through or adjacent to an electrical test coil which has been excited by an alternating current.

Eddy current testing of tubes is highly specialised requiring expertise and specialist equipment. A benefit of eddy current testing is that detection of defects is instant and can be reported immediately to site or operation managers. Eddy current array and other ultrasonic and electromagnetic equipment including instruments sensors software and robotic solutions to key industries such as aerospace energy mining power generation and transportation. For the best heat exchanger testing users can choose between a multiplex simultaneous injection instrument or a tubing array instrument with probes featuring either bobbin or array compatibility or ideally both.

Eddy current testing ect as a technique for testing finds its roots in electromagnetism. We have the most extensive experience and we develop the highest quality ect inspection products. Our high performance equipment and solutions includes ge s portable mentor em the nortec 500 series and the nexxis.
