About the FDIMR-L BT Back-to-Back Gauge

The electronic back-to-back distance measuring gauge is created for contactless measurement of back-to-back distance between railway wheels during repair, examination, check-ups and formation of the wheel sets. This gauge measures directly on rolling stock, therefore roll-out of the wheel set is unnecessary. This version can be used manually but also in combination with a bluetooth PDA.
