115/230 V Transformer Electro Magnet

The 115/230 V Transformer Electro Magnet is a replacement or repair component for the electro-magnet kits utilized in magnetic crack detection. Magnetic crack detection is a method used to identify cracks in ferrous castings by creating a magnetic field that attracts magnetic powder to surface-breaking flaws. This transformer is a vital part of the electro-magnet assembly within these kits.

The 115/230 V Transformer Electro Magnet is a crucial component designed for use in magnetic crack detection systems. Specifically intended as a replacement or repair part for electro-magnet kits, this transformer provides the necessary power to generate the magnetic field required for this non-destructive testing method on ferrous castings.

Understanding Magnetic Crack Detection:

Magnetic crack detection is an effective technique for locating surface and near-surface discontinuities, such as cracks, in ferromagnetic materials like iron and steel castings. The process involves:

1. Magnetization: An electro-magnet, powered by a transformer like this 115/230 V unit, is used to induce a magnetic field within the ferrous casting.
2. Powder Application: Fine magnetic particles (magnetic powder) are then applied to the surface of the magnetized casting, either dry or in a wet suspension.
3. Crack Indication: If a crack or other flaw is present that intersects the magnetic field lines (typically oriented between the poles of the magnet), it creates a leakage field. This leakage field attracts and holds the magnetic powder, forming a visible indication that sharply outlines the location and shape of the crack.
4. Inspection: The electro-magnet is moved across the surface of the casting to thoroughly inspect for any cracks, allowing for the full extent of any detected flaws to be identified.

Role of the Transformer:

The 115/230 V Transformer Electro Magnet is essential for powering the electro-magnet used in this process. It steps down the input voltage (either 115V or 230V depending on the setup) to the appropriate level required by the magnet to generate a strong and consistent magnetic field.

Note on Electro Magnet Kits:

While this listing is for the transformer component itself, complete Electro Magnet Kits for magnetic crack detection are available. These kits typically include a Power-Pak Electro Magnet, a quantity of Magnetic Powder, a Powder Spray Bulb for application, and a Toolbox for storage and transport. Examples of complete kits include the Electro Magnet Kit - 115V (Part # 400-1110-01) and the Electro Magnet Kit - 230V (Part # 400-1112-30) (not avail. on the website). This transformer is a vital part of the electro-magnet within those complete kits.

Important Limitation:

It is crucial to remember that magnetic crack detection, and therefore this transformer and the electro-magnets it powers, can only be used on materials that can be magnetized (ferrous castings). This method is not suitable for non-ferromagnetic materials such as aluminum castings.
