Weld Hole Detector DTS240

Weld Hole Detector DTS240

Typical applications

The DTS is an optical detector. In association with the EMR emitter, it is able to detect the weld hole made in order to locate the linking weld between two strips.

Main features

• High speed up to 1500 m/min,
• Use of high power LED for high detection margin and long life time,
• Interference suppression by modulated light,
• Designed for steel industry conditions,
• Heavy duty connectors.

Typical installation

Receiver and emitter are fixed perpendicular to the line axis in order to take the lateral deviation of the strip into account.The following conditions have to be held for a proper detection:

• The DTS field of view should completely cover the lateral position of the hole.
• The emission of the emitter should completely cover the lateral position of the hole.
• When there is no hole, the emitter should be completely covered by the strip regardless of the lateral deviation of the strip. For applications where the emitter is not covered completely by strip, DELTA has developed the DTR.
• The figure below shows a typical mounting arrangement and the table gives the field of detection for different distances between pass line and receiver / emitter.
