RM-CAT Corrugation Analysis Trolley

Rail corrugation and acoustic roughness measuring trolley for tracks and switches.
Suitable for vignola and grooved rails.

Product description:

Rail surface irregularities of the order of microns (0.001mm) in amplitude are important in the generation of wheel/rail rolling noise and vibrations. The CAT portable measuring trolleys is easy to carry and set-up and is suitable for obtaining continuous longitudinal measurements of irregularities on the rail surface.

CAT

Applications:

Monitoring of rail quality
Detection of corrugation and acoustic roughness
Detection and classification of both short and long waves
Assessment of mobile rail treatment results e.g. rail grinding and milling

Main characteristics:

Measurements that are highly accurate and repeatable
Relatively simple installation and setup
Contact measurement system using inertial sensors
Suitable for any track gauge
User-friendly software for acquisition and review of measurement data
Operation through notebook or tablet-pc
Robust yet light weight design
Extensive product support
