MiniProf Switch & Crossing is a high precision and portable tool for fast, reliable and extremely accurate cross-sectional profile measurements of switches and crossings for monitoring and analyzing the wear of the rails. It is equipped with Bluetooth, has an option for cable connection and is available for most types of switches and crossings.

The instrument extends to the opposite rail through a fixed rod, offering stability, gauge and track relative measurements. It can easily be adjusted to match various measuring scenarios and each measurement is performed conveniently in one single measurement in less than 5 seconds per profile.

Get instant results

Depths, widths, angles and precise information on the physical placement of the switch is provided instantly in real time view and is stored by the accompanying Envision software for onsite and post measurement analysis. This allows for evaluation of not only the profile of the individual rails, but also the geometry data of the entire cross-section.

Switch analysis & calculations

The MiniProf Envision software visualizes and calculates residuals and areas automatically.

Measurements can be compared in multiple ways and are easily exported to various formats.

GPS location

The MiniProf Envision software can log GPS locations for each measurement taken and attach onsite photographs to the particular measurement. This is very useful to identify special points of interest along the railroad track.

Super elevation and grade

A tilt sensor measures super elevation and grade automatically depending on system configuration. The values are stored with the measurement and can be displayed at any time. The range of the measured inclination is ± 30 deg.
