TyreGuard® External vs Internal Sensors Deliver Safer, Lower- Cost Performance

The bulletin examines valve- mounted TyreGuard® CE360 external sensors against typical internal sensors fitted inside OTR tyres on haul trucks, loaders, graders and support equipment. While both technologies were found to deliver comparable pressure accuracy and practical temperature monitoring for alarm and trend analysis, the report concludes that the real differentiator is what happens when a sensor fails or reaches battery end- of- life.

According to the analysis, internal sensors generally require full tyre removal, bead breaking, lock- ring handling and reassembly before a sensor can be replaced. In mining operations, that means added technician exposure to one of the industry’s highest- risk maintenance tasks, along with significant downtime and production loss.

By contrast, LSM TyreGuard® external sensors can be replaced in minutes at the wheel end without removing the tyre, allowing mines to restore full TMSystem functionality quickly and safely. The bulletin also notes that TyreGuard® external sensors are lower in hardware cost and can materially reduce unmonitored running after a fault.

Using a CAT 797 haul truck as an example, the report models avoidable production- loss exposure from internal- sensor replacement events at approximately $480,000 in a low case, $1.5 million in a typical case and up to $4.2 million in a high case for a single annual event. Across a 20-truck fleet over five years, the modelled impact rises to $105.6 million low case, $270 million typical and $648 million high case.

These findings reinforce TMSystem architecture as a critical fleet decision. The conclusion is clear: for mining fleets seeking safer maintenance, lower lifecycle cost and higher availability, TyreGuard® external sensors (also Conditioner Fluid compatible) offer a compelling operational advantage.
