MTS FlexDAC 20 Data Acquisition Systems
Acquire high-fidelity test data from bridge-based devices such as strain gages and load cells, and high-level devices such as accelerometers and thermocouples. Fast acquisition speeds, high-channel-count capabilities and synchronization with FlexTest controllers make MTS FlexDAC data acquisition units ideal for evaluating the behavior of full-scale and component structures under load.
Key Product Features
Integrated / Synchronized
Employs hardware-based clock synchronization with FlexTest controllers to yield extremely high data accuracy
Versatile
Can distribute data acquisition channels in any proportion across multiple test stations simultaneously
Accelerated Testing
Eliminates the need to synthesize data manually after testing, improving productivity
Accurate / Repeatable
Automated calibration quickly verifies and documents measurement accuracy
