General purpose testing machine data processing system

General purpose testing machine data processing system
Add-on software MSAT-0009 for the friction and wear tester

This additional data processing software controls the revolution speed and the contact load of the EFM series and other various friction and wear testers and can acquire and analyze friction data.

Setting	Measurement	Reference

Preset conditions to automatically perform stepwise control of contact load (pressure load P) and revolution speed (sliding velocity V) are required for friction test evaluation to collect data.	Friction force, contact load, revolution speed and temperature data can be acquired and then converted into various units to be displayed in a graph or table. Results can be output in an arbitrary combination of friction coefficient, contact pressure, sliding distance, sliding velocity, etc.	Data on the relation between PV value and friction coefficient can be displayed based on the step average of the measurement result.
