Hardware
The cRIO system with its rugged design and good value architecture consisting of very different measurement modules, the intelligent FPGA chassis and a high-performance real time controller, offers a high degree of flexibility for your measurement tasks.
- Synchronous acquisition with up to 28 channels with minimal space consumption
- Various signal types may be acquired (voltage, IEPE (ICP) conditioning, bridge amplifier for strain gauges)
- Continuous or intermittent recording, trigger condition may be defined individually for any channel
- Measurement of acceleration, velocity, displacement, force, strain, rpm, analogue and digital signals
