Roland Double Sheet Detectors are required in blank feeders, sheet destackers, robot loaders, blank washers, sheet conveyors, to provide tool and die protection for stamping presses.  Roland Double Metal Detectors for steel, aluminum, or stainless steel blanks are therefore an important precondition for press automation. Single probe double sheet sensors can be mounted directly into vacuum suction cups. Non-contact dual head systems are especially well suited for roll forming application,  mechanical and magnetic transfers.

Weld seam detection and positioning in tubes with magnetic flux leakage or eddy current sensors is necessary in pipe and tube bending machines, or in hydroforming presses to produce automotive components such as exhaust manifolds, head rests, side members, roll bars, or engine cradles.
The detection and elimination of welds  when processing coils in blanking presses, or cut-to-length lines makes the use of lower cost welded coils possible.

Nondestructive testing is necessary in continuous production processes to detect defects and quality problems online. Inspection systems based on the Eddy current and magnetic inductive principles are being used for this purpose. The Universal Fault Detector UFD40 has been specifically designed for detecting defects in semifinished materials such as wires, rods, tubes, and coils.
The magnetic inductive methods are being used in the tried and proven Steel Cord Inspection System SIS XP for the detection of so-called spacing faults when cutting and splicing steel cord material for the production of steel belted tires.

Thickness is an important process parameter for the prevention of tool or machine damage and quality assurance according to ISO 9000 in blanking presses, slitting lines, cut-to-length lines, scroll shears and other coil processing machinery. Continuous thickness measurement with protocols according to SPC criteria makes the monitoring of the cost of purchased material possible.

During automatic filling of pharmaceutical blister packages underfill and overfill conditions cannot be tolerated for a medical product. Verification of content is therefore necessary. The Blister Package Comparator with its eddy current sensors system is free of inertia resulting in very high inspection velocities with only minimal space requirements of about 100 mm (4 in.) within the transportation line.
