BMT-D – SERVO HYDRAULIC DYNAMIC FATIGUE TEST MACHINE
The BESMAK® BMT-D Series is a servo-hydraulic fatigue testing system engineered for dynamic and static material testing across a wide range of industries. These systems perform low-cycle and high-cycle fatigue, crack growth, fracture toughness, and durability tests with exceptional precision and control. Designed with a high-stiffness load frame and powered by advanced servo-hydraulic technology, the BMT-D series offers stable force application, and long-term reliability. Equipped with the SEMATRON digital controller, fatigue-rated load cells, and BESMAK® Universal™ dynamic testing software, it provides a complete solution for both standard and custom test applications.
- Up to ±1000 kN capacity

FRAME
Test system consists of a double-column fixed cross-head type rigid frame. Actuator mounted from the upper cross-head of frame. Test frame is feasible for dynamic tests.
LOAD MEASUREMENT AND CONTROL
Test system comes with a fatigue rated load cell for load measurement and control. Test system is feasible to carrying out load controlled test with class 1 according to EN 7500-1 standard. Load control resolution is 20 bit. Load cell calibration can be carried out between 2% to 100% of maximum capacity.
DISPLACEMENT MEASUREMENT AND CONTROL
Test system comes with a MTS brand SSI type non-contact electromagnetic linear displacement sensor with 1 micron measurement and control resolution. Displacement sensor has very fast response. Displacement sensor is placed inside the actuator for high accuracy.
ELECTRONIC CONTROL UNIT
Test system comes with a special closed-loop controlled electronic control unit. The electronic control unit of system is (German made) with 10000 samples per second data acquisition speed. Accurate synchronization between frame and sensors will be done/controlled by advanced PID or close loop configuration. Electronic control unit has total 5 channels (2 internal, 3 external). Due to these channels, electronic control unit can control upto 5 no. sensors at same time. Electronic control unit is feasible to attach and control video extensometer, laser extensometer, LVDT, automatic extensometer, strain gauge, load cell, SSI and TTL type sensors.
