Product Data Sheet – Universal SW

Stationary Crack Detection Units

Our Universal SW stationary test benches are suitable for testing work pieces with clamping lengths from 1,200mm to 3,200mm. The clearance coil diameters of the basic units are 400 or 500mm. Universal benches can process test pieces with a maximum weight of 300kg (standard) or 1,000kg (optional).

The standard Universal test benches of the SW series are equipped with two AC circuits. This allows the indication of longitudinal and transversal cracks at the same time. For longitudinal cracks, use axial current flow; for transversal cracks, use coil magnetisation.
