About the FDK Wheel diameter gauge
The Wheel Diameter Measuring Gauge FDK Series is engineered for high-precision diameter measurement of railway, tram, and metro wheelsets. It delivers measurement accuracy of ±0.1 mm with a selectable resolution of 0.1 mm or 0.01 mm. The electronic gauge is lightweight (0.5 kg) and battery-powered, making it ideal for mobile and on-site maintenance teams.
Usage conditions
The gauge is suitable for operation in harsh field conditions with a temperature range of -15 °C to +55 °C. It operates using two rechargeable AAA batteries and allows up to 1,000 measurements on a single charge.
Possible applications
- Railway depot maintenance
- Tram and metro fleet inspections
- Wheel wear monitoring
- Wheelset assembly and quality control
- MRO in transport infrastructure
