SPG-3S' (standard gauge model)
'SPG-3N' (narrow gauge model)
The Switch Profile Gauge is a new system for automated turnout inspection and maintenance.
The system adopts the light slice method using a laser slit light source and two-dimensional CCD cameras. The system simultaneously measures the information necessary for calculating the wearing depth of rails and crossings, back gauges, flangeway widths, and track geometry. The system automates conventional manual track inspections and produces databases of measurement data which incorporates office automation technology in the maintenance and management task.
