Electromechanical Load Frame
Electromechanical load frame with two-column vertical standing assembly and threaded columns for crosshead adjustment and closed-loop control of axial load/stress or axial displacement/strain. Servo control with closed-loop feedback from any of the eight (8) input channels or any real-time calculated function. The eFRM load frame can accommodate a large range of test fixtures. GCTS offers a large range of test apps for specific standards or custom test methods. GCTS offers several eFRM models, all of which have a 100 mm stroke with four (4) ADC channels with excitation (5 VDC or 10 VDC), simultaneous sampling, internal filtering, and selectable input range (from ±2.4 mV to ±20 V) and four (4) ADC channels with ±10 VDC fixed range.
Power Requirement: 90-260 VAC, 50-60 Hz, 8 A @ 1 KVA
* Load Capacity up to 90 kN Available
* Dynamic Electromechanical Load Frames Available
