Eddy current testing system with a clever sensor design

• Reliable quality assurance for your semi-finished products with diameters from 2 to 20 mm in terms of longitudinal defect detection
• Minimum conversion times when changing to a different diameter through replacement of the entire sensor disk
• High durability since the sensor has no moving parts
• Ideal for installation in production lines (drawing lines) due to compact design
• High material throughput speed of up to 2.88 m/s with gap-free testing
• Highly precise defect signal output with liftoff compensation system

The RS20 rotating system for the nondestructive eddy current testing of round metallic products such as tubes, rods and wire with diameters from 2 –20 mm achieves high throughput speeds and is ideal for installation in production lines due to its compact and rugged design.

The new sensor design
During the production of rods and wire with different diameters, the eddy current testing system needs to be reconfigured every time the diameter changes: the new diameter is set, the guide sleeves are exchanged and the testing parameters are adjusted. Changing the diameter and then checking the setting with a sliding caliper is often a cumbersome, complicated and lengthy task.

In the new RS20 rotating system, PRUFTECHNIK NDT GmbH has taken an entirely new approach and now exchanges the complete sensor unit, each with a specific diameter.

The advantages of this solution lie in the speed with which the diameter can be changed – usually within three minutes – but primarily in the durability of the sensor units, which contain no moving parts and are encapsulated.
