BMT-C/E – SERVO ELECTROMECHANICAL CREEP/STRESS RELAXATION TEST MACHINE
BESMAK® BMT-C/E Series Electromechanical Creep Testing Machines provide an alternative solution for long-term creep and stress-rupture testing using a fully electromechanical load application system. They feature a high-stiffness 4-column frame with a dual lead-screw drive, ensuring precise and stable load application over extended periods. These machines are ideal for laboratories that require long-duration creep testing without the need for a hydraulic infrastructure. The BMT-C/E series is engineered to meet ASTM E292 and other international creep test standards, delivering accurate results over thousands of hours of operation. Despite their high capacity, they require no special foundation or anchored base, and built-in vibration isolation (e.g., Sylomer® dampers) ensures smooth, consistent load control. Overall, the electromechanical creep frames offer reliable constant-load maintenance with minimal maintenance and operating costs.
- High stiffness and precision provided by a 4-column frame with dual-screw drive design, offering excellent stability and flexibility.
- Precision axial alignment (per ASTM E292 requirements) achieved through guided crosshead movement and specialized load train seating..
- No special foundation or mounting pit required – the system can operate on a standard lab floor.
- Yük şasesi altında Sylomer® sönümleyicilerle entegre titreşim yalıtımı, çevresel titreşimleri en aza indirir.
- Integrated vibration isolation using Sylomer® dampers beneath the load frame to minimize environmental vibrations.
- High-resolution crosshead encoder and load measurement channels give excellent control and measurement fidelity.
- Long-life, brushless AC motors ensure high durability and low maintenance operation.
- Fast control loop cycle (adjustments every 6 ms) for stable long-term load control.
- Standard load capacity configurations of 50 kN or 100 kN (other capacities available on request).
- Crosshead stroke of 1290 mm to accommodate elongation of specimens during long tests.
- Return speed of 100 mm/min for efficient unloading and setup between tests.

Servo Electromechanical Creep Testing Machine, can work on tension compression, bending and long term-creep tests and on both displacement/deformation mode and load control mode (with and without extensometer optional). 4 column/2 column rigid construction.
LOAD MEASUREMENT AND CONTROL
- With a special creep type load cell of class 0.5 for long-term tests
- 1 kHz data accusation Close-loop electronic controller
- Crosshead moving speed (mm/min): 0.001-250.
THE ELECTRONIC CONTROL UNIT
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 (Sensors are optional). Special Eeprom sensor plugs can store calibration and sensor data inside it. Due to this feature control unit can read sensor and calibration data even if user change it with new unit.
User can read and control each attached sensor with control unit, for example; 2nd load cell, LVDTs and extensometers. can perform load and displacement controlled test, position measurement and control with position encoder of 1 micron resolution, Load channel with a resolution of 20bit, adjustable displacement control in between 0.001 – 250 mm/min, testing software, 32 user defined result parameters (connected to load and position), result can be transferred to Excel format(Raw Values). It has periodic saving function for long-term creep tests.
Specially designed close loop and rapid cooling system will be provided with hydraulic unit of system to prevent oil from heating during the test.
