Tester HFRR High Frequency Reciprocating Rig   Next Generation HFRR lubricity tester with real-time force and stroke control, piezo sensors, and wide temperature range. BROCHURE

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) 
• Load Range up to 20N (More ranges 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.

a fretting machine like no other

Test the surface damage that occurs between two contacting surfaces. Analyze two-body abrasion, adhesion, and/or fretting fatigue wear.

Down Force Control Real time down force control to account for contact wear.     Voice Coil Electromagnetic actuator that imparts linear reciprocating motion. Dependent on the test additional coils can be installed on the tester to double the force range    High Accuracy Position Control   The most accurate and precise displacement control in the market. Up to 1nm resolution and micron level of accuracy. Extremely low noise. High responsiveness for dynamic performance of system.    Environmental Control   Study fretting wear  across a wide range of temperature.

Unmatched Waveform Control Without 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 Measurement   The 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 Sensors Sensors 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 Holder   Customizable liquid and sample holders for standard and non standard tests.
