Application

The DTS is an infrared scanning detector. In association with the EMI infrared emitter, it is able to detect the weld hole made in order to locate the linking weld between two strips.
The DTS sensor is sensitive to infrared emission and therefore is not disturbed by the reflection of sodium vapour or fluorescent ligths on the strip.

Introduction

The DTS is a scanning detector. The field of detection is scanned by a multiple mirrors system. When it encounters infrared radiation, the active element of the sensor produces a signal that is processed by the built-in electronic unit and delivers a logic output. The output is kept for 500 ms after the end of the detection.

Working Principle

The DTS sensor detects the infrared emission emitted by an EMI through the weld hole. Sensor and emitter are fixed perpendicular to the line axis in order to take the lateral deviation of the strip into account.
