POPIS PŘÍSTROJE:
- Real-time down force control
- 1 to 200 Hz, 10 µm to 2.8 mm
- Real time friction with piezo load sensors
- Room to 180 °C (cooling and up to 400°C options available)

Evaluate fuel lubricity, predict the performance of additives, and study friction wear with our HFRR high frequency reciprocating rig. This next generation Rtec Instruments HFRR testing machine contains programmable force control (no dead weights). Combined with piezo sensors to measure real-time friction. The ease of use, flexure based design makes this tester highly reliable and repeatable. Test collected samples from field or for research purpose. The FFT-M provides a fully automated and computer controlled test. Setup is easy to calibrate and comes with standard oil and samples. Each tester conforms to several ASTM standards including the most widely used ASTM D6079. In addition to standard testing, the wide stroke, frequency, and load range allows development of new custom test methods. Perfect for understanding next generation fuel additives.

 Unmatched Waveform ControlWithout the friction of rolling or bearing, the magnetic flexure based design provides the control required for the most sensitive of tests. The unique controller adjusts to friction changes to maintain the stroke control in real-time.  Friction MeasurementThe fretting tester comes with high frequency piezo sensors to measure real-time friction. Ultra low noise amplifiers aids in detection of minute changes in friction with ease.  Additional In-line SensorsSensors such as acoustic emission to detect onset of cracks, and ECR to measure surface resistance changes to gain more insight on the material interface.
 Liquid Containers, Sample HolderCustomizable liquid and sample holders for standard and non standard tests. |
FEATURES
|
Next Generation With stroke control from 10 µm, the Rtec Instruments SRV tester simulates many test conditions that are not possible using any other commercially available tester.
