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?
您测量的是什么? 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!

We’re excited to be part of iaf 2025 in Münster, Germany! Join us at stand M-320 in Halle Mitte, where we’ll be showcasing the MiniProf profile measuring systems in action. Whether you’re an old friend or a new face, we’d love to connect. Stop by for a live demo and a chat about how MiniProf can support your work.
Should you be attending Railway Interchange in Indianapolis, USA, we invite you to stop by MiniProf agent KLD Labs – an ENSCO company at booth 3015, where you can explore the MiniProf systems and the advanced Envision software.
Uncover the benefits of the highly secure and dependable MiniProf full-contact profile measurements and learn how the Envision software can enhance your everyday operations. Feel free to arrange a meeting beforehand by contacting the KLD MiniProf team.
The MiniProf team is here for you! If you have any questions about our MiniProf products, Envision software, Criterion for Android, local agent details, re-calibration or any of our other services, do not hesitate to contact us – we will be pleased to assist.
