全接觸式測量原理

在完整測量過程中,設備的磁性刀鋒狀滾輪與實際測量剖面保持全接觸,確保測量的是實際剖面。選用高精度旋轉式光學編碼器,單一測量檔中含有30000個單獨的採集點,測量精度範圍9-11微米。MiniProf全接觸式測量方式獲得測量剖面的真實狀態,精度優於市場上鐳射設備的10倍以上。

全接觸式VS.非接觸式

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?

What do you measure? The actual profile or the accumulated surface?

Full contact
Measures the true profile with highest accuracy
Cuts through surface contaminants
Not sensitive to light and reflective surfaces
Human tactile sensing and real-time feedback
Non-contact
Makes a scanned picture of the surface
Does not distinguish between dirt and profile
Sensitive to light and reflective surfaces
No tactile or visual feeling with the profile

No sensitivity to reflecting light

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.

Never underestimate the importance of a full contact measurement!
