USF-2000A - Specs
Ultrasonic Fatigue Testing System
Specifications
| Test frequency | 20 kHz ±500 Hz (recommended test range: 20 kHz ±30 Hz) Note: The test frequency is determined from the resonance frequency of the sample. |
|---|---|
| Vibration at horn tip | ±10 to ±50 μm |
| Test stress range | Stress given ±10 to ±50 μm displacement of sample Note: Stress values depend on sample shape and physical property values. |
| Stress ratio | -1 |
| Testable materials | Materials that can be resonated at 20 kHz and generate minimal heat during resonance Example: High-strength steel, duralumin, titanium alloy, aluminum, etc. |
| Not-testable materials | - Materials that cannot resonate at 20 kHz - Materials for which samples are difficult to attach - Materials that generate significant heat during resonance at 20 kHz, due to friction Examples: Resins, ceramics, etc. |
| Power Requirements | 3-phase 200 V: 2 kVA (air compressor) , 1-phase 200V: 3.5 kVA (ultrasonic fatigue testing system) , 1-phase 100V: 1 kVA (computer, displacement logger, air dryer, etc.) |
| Standard contents | USF-2000A Ultrasonic Fatigue Testing System main unit (including table), ultrasonic resonance system, control computer,ultrasonic testing control and measurement software, and cooling unit (air dryer and compressed air lines) Note: Air compressor for cooling is not included. |
| Required optional products | Air compressor (for regions with 50 Hz or 60 Hz power) 3-phase 200 V: 2 kVA |
| Displacement measuring system (eddy current displacement gauge with 0.5 μm resolution) Note: A high-speed data logger or digital oscilloscope is required separately for reading voltages output from the displacement gauge. |
|
| Displacement gauge calibrator (CDE-25 C1 high-performance micrometer) |
Note: Systems can be selected without an air compressor in cases where the customer will supply the compressed air. A 150 L/m flow rate of compressed air at a minimum 0.2 MPa is required.
