The great advantage of GEA sensors over conventional measurement solutions is that they can be directly connected to a computer with GEA Lab software installed, without the need for dedicated, proprietary memory cards. This type of connectivity increases the number of sensors that can be connected, thus allowing for the development of more effective and highly cost efficient monitoring systems. However, such solutions are somewhat limited when it comes to performing complex measurements. In particular, the cable length in this configuration is limited to 60 meters, and intra-sensor synchronism is limited (by USB technology) to 100 ms. SyncHub overcomes these limits. It facilitates the use of cables that are up to 1 km long, without the need for intermediate amplifiers or the use of special cables. This solution also guarantees synchronism between sensors that are used for modal-analysis testing. A single SyncHub module can have up to four sensors connected to it, all of which can be used simultaneously – that means up to 16 sensors can be interconnected in master-slave mode.
