Confocal controllers for precision, high speed thickness and distance measurements

03 May 2012

Micro-Epsilon's new confocal controllers offer faster measuring rates, up to four times better signal-to-noise ratios, and up to 100 times faster real time surface compensation for difficult-to-measure surfaces. The DIN rail mounting controllers will measure the thickness of single and multi-layer transparent materials, as well monitoring liquid fill levels, inspecting bore holes (or small cavities), and measuring transparent, reflecting or matt surfaces.

The confocalDT 2451 and confocalDT 2471 controllers replace the company’s existing IFC2401 and IFC2431 confocal controllers, and can be used with all Micro-Epsilon confocal sensors, including the latest miniature 4mm and 8mm diameter units in axial or radial versions.

For the first time, the controllers benefit from a rugged industrial design and use a high performance CCD array as the sensor element. The confocalDT 2451 utilises a white LED as the light source, which enables measuring rates up to 10kHz, while the confocalDT 2471 provides up to 70KHz measuring rate using an external Xenon light source. Both controllers are provided with Ethernet, EtherCAT, RS422 and analogue output interfaces.

Most conventional confocal controllers use an integral fan and air vents in order to cool the controller during operation. The new confocalDT 2451 and 2471 use a passive cooling system that does not require a fan or air vents, which greatly improves the controller’s protection rating and longevity.

The new controllers are simple to set up and operate. The user can remotely configure measurement channels using the intuitive, web-based software via Ethernet. The user does not need to install any other measurement software.
