在完整测量过程中,设备的磁性刀锋状滚轮与实际测量剖面保持全接触,确保测量的是实际剖面。选用高精度旋转式光学编码器,单一测量文件中含有30000个单独的采集点,测量精度范围9-11微米。MiniProf全接触式测量方式获得测量剖面的真实状态,精度优于市场上激光设备的10倍以上。
Contrary to a full contact measurement, similar non-contact laser-based handheld measurements are made without actual contact to the measured profile. This demands an extremely high level of profile attendance prior to measuring as the laser does not distinguish between the profile and any layers of dirt, oil, grease etc. If the profile is not cleaned thoroughly, a laser-based measurement will reflect the profile surface plus any unremoved layers. Obviously, if the collected data does not reflect the actual profile, it can have critical consequences for following decisions in maintenance, safety and budgets. Do you trust your measurement?
A MiniProf system is suitable for use in any working environment as the full contact measuring principle is not challenged by environmental factors.
In contrast, the non-contact measuring principle can be severely challenged by reflective surfaces from the sun, white frost, rain drops, dew on the rails etc. Even reflections from newly turned wheels or rails can disrupt a non-contact measurement.
The environmental sensitivity should therefore be considered carefully when working with laser-based equipment, especially in specific geographical areas dominated by sun, rain or snow and in manufacturing and reprofiling facilities.

The TRB Annual meeting in Washington D.C. is coming up soon and Greenwood Engineering will be there presenting our full contact MiniProf profile measuring systems. We welcome you to stop by our booth 521 for a chat and a demonstration and look forward to showing how safe, accurate, consistent and reliable profile data can easily be obtained by using the small, handheld MiniProf systems.
In order to schedule a meeting in advance with our Director of Railway Division, Mr. Benny Andersen, do not hesitate to contact us.
