Tribometer

The tribometer was specified with a motor/controller combination that offered a better than 1000:1 speed range along with a serial interface so that Stribek curves can be generated under computer control. The normal force is applied pneumatically and it would be trivial to apply computer control to this as well. The system is designed so that many sites can be multiplexed against heated rotating shafts and measurements made using very small volumes of oil. The design was patented and this currently held by ICI (now a subsidiary of Akzo Nobel).
