MiniProf BT Wheel is a high precision, lightweight and portable tool for performing fast and reliable cross-sectional wheel profile measurements to monitor and analyze the wear of wheels. It is equipped with Bluetooth, has an option for cable connection and comes in few variations depending on your requirements. Magnetically attached to the backside of the wheel, the wheel profile is measured in less than 5 seconds and a complete railroad car in less than five minutes.
Get instant results
Wear parameters such as Sd, Sh and qR values are displayed instantly after each measurement in real time view. Numerous additional calculations and alignments are included in the powerful Envision software for basic to advanced data handling, analyzing and reporting
Wheel analysis & calculations
The MiniProf Envision software visualizes and calculates residuals and areas automatically.
Measurements can be compared in multiple ways and are easily exported to various formats.
Reprofiling
The MiniProf BT Wheel system is ideal to use before and after reprofiling of the wheels to determine when to reprofile and how much material to take off during the reprofiling process. This leads to precise reprofiling and improved lifetime of the rolling stock due to the unmatched high accuracy of the MiniProf system.
Fast measuring with schemes
When measuring multiple profiles, the MiniProf BT measuring scheme is a very strong tool for clear identification of each profile in advance and for simplifying and reducing the measuring process even further.
From tram vehicles to locomotives
MiniProf Wheel Mini is the smallest member of the MiniProf Wheel family. With its compact and lightweight design, it is a versatile tool for measuring most types of wheels from compact tram wheels to locomotive wheels.
With only a small 100 mm backplate, it fits right in the palm of your hand and can be used even if only limited measuring space is available. It is fast and easy to operate and provides the same excellent profile accuracy and reliability as always, but without the diameter reading.
For improved diameter measuring
MiniProf Wheel 400 is equipped with a wide 400 mm backplate and is our best option for profile and diameter readings in one single measurement.
Due to the large backplate, diameter readings are improved significantly and are three times less sensitive to the state of the wheel and measuring process compared to MiniProf Wheel 250.
As with most similar tools, the diameter is based on the common used Versine measuring principle and an assumption of an ideal wheel without local deformations. This should always be considered when handling diameter.
