From the rail to the result
Engineering ownership
Our work spans sensing arrangements, electronic hardware, embedded firmware, applications and integration. We understand how measurements are made and how to investigate problems in the field.
Direct specialist support
Draw on the people behind the technology for application definition, installation, commissioning, diagnostics and long-term support.
Practical installation
Track-mounted measurement systems can generally use the existing rail structure. Compact equipment, low-power options and remote communications help address sites with limited infrastructure.
Operational integration
Vehicle identification, reporting and process interfaces are considered as part of the application, working with customers, engineering consultancies and systems integrators.
Installed experience
A current-generation Dynamass upgrade at Karara
Karara Mining uses a solar-powered Dynamass T4i to verify rail-vehicle loading before product travels from its remote Western Australian mine to Geraldton Port.
The original T4 operated from 2012 until July 2024, when it was replaced by the current-generation system. OTT’s product and installation expertise combined with HMA’s local coordination, logistics and on-site assistance.
