Typical applications

The DTR 340 is a diode array detector. In association with the EP or EM light emitter, it is able to detect the weld hole made in order to locate the linking weld between two strips.

General description

The Weld Hole Detector DTR 340 consists of a lens, a linear diode array, and a processing unit.
The Emitters EP and EM use a fluorescent tube and a high frequency electronic ballast to generate light modulation at 28 kHz.
The use of a high frequency tube results in constant light conditions as regards to the minimum exposure time of the sensor, to avoid 100 Hz (or 120 Hz) over modulation problems associated with standard tubes.

Features

The DTR Weld Hole Detector has been designed for heavy industry with:

• Adjustable mounting stand (2 axes). In case the sensor needs to be replaced, it can be easily dismounted from the stand, thus keeping the alignment.
• Protective hood.
• Control panel beneath a hinged cover at rear.
