Flat Washer (Spacer) Thickness Measurement System

RIFTEK: The System is developed on the order of one of the lead designers and manufacturers of the thermoelectric modules.

The task was to develop and to produce precision automatic machine for contactless measurement of thickness of spacers used in production of thermoelectric modules.

The main features of the System are:

• Thickness measurement range – 0,6...3,5 mm,
• Measurement accuracy – ±5 μm,
• Spacers diameter – 25,4 mm,
• Productivity – >1000 pcs/hour.
• System parameters can be changed for the specific task

Operation of the machine is based on the principle of laser scanning of the spacer by two laser triangulation point sensor, located on the opposite sides of the spacer. When the spacer is in the measuring zone, it is rotated and translated and, as a result, the thickness is measured in a spiral on the spacer surface, which allows registering the extended surface defects.

System Manual and Video Presentation are available on RIFTEK’s website.
