The IEM Wheel Diameter Gauge enables operators to generate accurate wheel circumference or diameter readings without the use of a wheel tape. It is now practical to monitor wheel diameter variations during routine scheduled maintenance inspections while the wheel is still mounted on the car or locomotive.

Key Features and Benefits:

  • Measures in US or Metric units.
  • Lightweight and easy to carry.
  • The power supply can be charged directly within the gauge, eliminating the need to replace batteries.
  • Fast and Accurate: Readings of mounted wheels can be accurately generated in less than 30 seconds.
  • Incorporates an averaging algorithm that eliminates the influence of surface defects when taking measurements.
  • An optional Bluetooth interface can be added to transfer measurement results into a wheel-set wear database management system.

The Wheel Diameter Gauge will quickly measure worn wheel diameters to within 0.25mm (0.010 inches) and can verify the reliability of wheel truing operations. Optional software can automatically compute crucial wheel to wheel and axle to axle wheel size variation.
