Product Advantages

High-Frequency Stability: Advanced electromagnetic actuator maintains 0.1–15 Hz frequency range with ±0.05% force accuracy.

Ultra-Precision Loading: 50 kN axial force capacity with 1 N resolution for submicron displacement control.

Dynamic Load Control: Programmable R=0.1–10 load ratios with real-time stiffness compensation.

Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with 20±2 g/L protein concentration.

Extended Durability: Capable of 10+ million cycle testing with <0.2% drift in calibration.

Modular Design: Six-station configuration allows parallel testing of multiple specimens.

Product Features

Electromagnetic Servo Motor: 50 kN axial force capacity with programmable load ratios (R=0.1–10).

Triaxial Strain Gauge: Measures axial/radial strains simultaneously (0.1 με resolution).

Dynamic Load Control: 0.1–15 Hz frequency range with programmable waveforms (sine, square, random, custom).

Thermal-Mechanical Chamber: ±0.3°C temperature stability with integrated humidity control (10–95% RH).

High-Resolution Imaging: Optional integration with micro-CT systems for in-situ crack analysis.

Safety System: Emergency stop, overload clutches, and laser-based specimen breakage detection.
