materials in coils
Sensor
For tool protection in front of cutting lines, presses, tube mills,
and other metal forming machinery with automatic feed of material
Filtering and analysis of sensor signal
Fail - safe operation
Visual display of signal level
One constant magnetic field for all sheet thicknesses up to approx. 3 mm (0.12 in)
Improved dynamic performance at variable surface speeds
WELD SEAM DETECTION SYSTEM SND8 - NS9SC
Application
The automatic processing of coils and strips requires the dependable detection of weld seams. This applies to body
shops in the automotive industry or the production of welded tubes and similar products.
Weld seams that are not detected in the production process may lead to the destruction of dies and machine break
down, faulty production and costly repairs. The Weld Seam Detector SND 8 has been specifically developed for such
applications.
The sensor NS9SC was specifically designed for butt welds in coils up to a sheet thickness of approx. 3 mm.
Measuring Principle
The sensor reacts to the magnetic properties of the materials. Weld seams lead to characteristic changes in the
magnetic field. These changes are detected by the sensor and processed by the control unit resulting in a switch
signal for the machine controls.
Sophisticated methods of signal filtering and analysis are applied to discriminate between noise and the weld seam
signal.
