ILD-1000 Light Sensor for Welding Process Control

Manufacturer: Pantron Instruments
Category: Infrared Photoelectric Amplifiers

Pantron introduces the new light sensor ILD-1000. It is used for the detection of intensive, non-uniform light that typically arises from arc welding and laser welding of metallic pieces.

This device detects the existence as well as the non-existence of an arc and is made for error detection for automatic manufacturing processes. The system consists of the evaluation device ILD-1000 and the sensor IR-M12VA.

The system was developed and tested in collaboration with a leading global supplier of robotic systems and welding plants. It is already successfully established by important automotive suppliers, rolling bearing and plant manufacturers.
