TE93 精密旋转试验机
TE93 PRECISION ROTARY TRIBOMETER 

ASTM G99, ASTM D3702

TE 93 Precision Rotary Tribometer provides a lower load range than the standard TE 92 Rotary Tribometer, on which it is based. The incorporation of a linear air bushing in the loading and friction torque assembly allows precise control of the load in the range 1 to 1,000 N and corresponding precision in the measurement of friction torque. Load is applied by means of servo controlled pneumatic bellows with force transducer feedback. The unit is specifically designed to run tests in the thrust washer and three pin on disc test configurations, with on-line measurement of friction, wear displacement (by capacitance probe) and sample temperature.
