In contrast to the standard single head MiniProf BT systems, the MiniProf BT TwinHead systems measure both left and right profile together. This makes it possible to obtain a highly accurate relationship between the two profiles, which is especially important in analyzing running characteristics for rolling stock using for instance equivalent conicity studies. The MiniProf BT TwinHead systems are available for rail and wheel profile measurements.

Two measuring heads

The MiniProf BT TwinHead systems are constructed similar to the single head systems, but consist of two measuring heads mounted on a fixed beam. The two opposite profiles are measured consecutively one by one. The measurements are stored and are accessible as individual profiles and together in pairs in one common coordinate system. This provides a high accuracy on the gauge and a precise knowledge of any rotation of the profiles which is a crucial part of any wheel and rail interaction study.

Equivalent conicity

With trains going faster every day, there is an increasing demand for better travel comfort as well as insurance of a high degree of safety. For this purpose, it is very important to look at the wheel and rail interaction, studying how the contact geometry behaves. The equivalent conicity is an extremely useful parameter when investigating this dynamic interaction between railway vehicle and track.

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.

Our Director of Railway Division Mr. Benny Andersen and Area Sales Manager Ms. Dorte Overmark Rasmussen will be there to assist you. In order to schedule a meeting in advance, do not hesitate to contact us.

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.

How can we assist you?

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.
