Laser Micrometers for very high accuracy diameter measurement The XLS (eXactum Laser Scan Micrometer) series Laser Gauges represent the latest technological development in laser scanning micrometry, featuring record performance. With their built-in and very powerful electronics, the XLS micrometers can be used as Stand Alone, Intelligent Diameter Sensors. When programmed with a Dedicated Software and completed with external Display Units and Operator Panels, they can be the hart of Dedicated Laser Measuring and Control Systems, for the on-line control of a variety of different products.

Operating principle Intelligent Diameter Sensors The Laser Gauges use a visible Laser Diode as a high intensity, monochromatic and coherent light source: a thin beam of this light is then collimated onto the object to be measured. The laser beam is deflected at constant speed by a turning mirror positioned at the focus of a transmitting lens, so as to obtain a parallel-moving scanning beam in the measuring field. During the scanning period, the laser beam intercepts the object being measured and casts its shadow onto the receiver. The duration of the shadow is proportional to the...

Non contact measurement: moving parts, hot or soft, can be easily gauged, in such conditions that would be off-limits for any other instrument. Permanent self-calibration: the measuring accuracy is guaranteed over time and periodical remastering is no longer required. Wide measuring range: parts of different size can be measured, without any pre-setting. Ultra high accuracy: ± 0.03 μm repeatability (T = 1 , ± 3 s ) Electronic linearization: the “error mapping” of each gauge makes it possible to compensate by software all errors due to optical aberrations Insensitive to product speed and...

Competitive Features New electronics, based on an ARM-7 type processor, 16Mb RAM / 8Mb Flash Memory, clock 74 MHz., FPGA (Field Programmable Logic Array 50,000 gates) and DSP (Digital Signal Processor) for high speed data processing. Internal temperature check: a sensor measures the internal temperature and shuts the gauge down when the operating temperature exceeds the allowed limit. Two fast digital inputs for triggering signals, metre counting, etc. sequences immediately identifyes possible malfunction conditions. Internal digital sampling of the video signal: serial signal downloading...
