Need help or have a question?
Rtec Instruments’ two roller tribometer has several key design features that makes it the only commercially available tester to run a wide set of conditions and in-line inspection on the same platform. With high data acquisition of 200 Khz, the TwinRoller-3000 obtains high precision measurements.
Closed-loop Patented Force Sensor
Capacitive and strain gauge force transducers work across a wide range with no drifts. Real-time servo closed-loop force control. This allows the creation of automatic torque vs load and speed curves.
Precise Temperature Control
Closed-loop temperature controller. From -35 to 150°C
In-line Torque Measurement
Self aligned in-line high resolution torque sensors to quantify surface dynamics in real-time.
Accurate Determination of Failures
The twin roller tribometer can accommodate various in-line monitoring sensors to quantify real-time surface dynamics. (acoustic, electrical, etc.)
High power, high speed, real-time speed control allows for repeatable data generation.
Integrated In-line Imaging
Image surface with nm resolution without taking sample out of the chamber. Integrated 3D profilometer to look at surface change during the test.
Many Configurations Are Possible
Rtec Instruments’ Twin Roller Tribometer comes in several application specific configurations.
Twin Roller Tribometer Test Data
Data shows coefficient of friction results from rolling contact fatigue setup. The surface treatments were done on one sample. Data shows which improvement in RCF life after the thermal spray coating application.
Sample 1 – uncoated
Sample 2 – thermal spray coating
- 500 N force
- SRR from 0 to 0.6
- Temperature 70°C
Two Roller Machine Solution
The twin roller machine is used extensively across a wide range of industries and applications. It’s used to analyze lubricants, contact fatigue life, and electrical contact resistance under various slip ratios.
