Technical Specifications

High-Rigidity Load Frame

• The BMT-D test system features a double-column fixed cross-head rigid frame designed to provide maximum structural stability during high-frequency dynamic testing. The actuator is securely mounted on the upper cross-head of the frame, providing a robust configuration for precise dynamic and fatigue testing applications.

Load Measurement and Closed-Loop Control

• The servo-hydraulic fatigue testing machine utilizes a fatigue-rated load cell for exceptionally accurate load measurement and feedback control.
• The system supports load-controlled testing with Class 1 accuracy according to EN 7500-1 standards. Featuring a 20-bit load control resolution, the load cell can be calibrated between 2% and 100% of its maximum capacity. This closed-loop control architecture provides stable and repeatable force application during demanding cyclic and fatigue tests.

Displacement Measurement and Control

• The BMT-D Series incorporates a non-contact electromagnetic linear displacement sensor with a 1-micron measurement and control resolution. Installed directly inside the actuator, this sensor provides ultra-fast response times and precise displacement measurement accuracy during dynamic testing procedures.

Electronic Control Unit

The BMT-D is equipped with a specially engineered closed-loop electronic control unit featuring high-speed data acquisition up to 10,000 samples per second.

Advanced PID and closed-loop configurations enable seamless synchronization between the load frame and connected sensors.
