Product Description

RPMI-Wheel Rail Profile Measuring Instrument

RPMI-Wheel is a high precision, lightweight and portable tool for performing fast and reliable cross-sectional wheel profile and wheel treadwear measurements to monitor and analyze the wear of wheels.

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. 

RPMI-W is based on the important full contact measuring principle where a magnetic knife-shaped measuring wheel provides constant and direct contact to the actual profile surface during the complete measuring process.

Concerns about dirt and oil are minimized as the full contact measuring wheel cuts through the layers on top of the profile and collects the actual profile, not just a non-contact picture of a surface.

RPMI-W can be performed in all types of working environments as the full contact measuring principle is never challenged by reflecting light, humid weather, white frost etc.
