Product Description

The GRAS 12BA (1 Channel), GRAS 12BE (2 Channel), GRAS 12BB (4 Channel) offer USB-powered, high quality CCLD inputs for acoustic and vibration testing. USB 2/USB 3 connection provides the units with power and supports TEDS. The high quality analogue signal is routed via a dedicated, separate (BNC) connector.

The GRAS 12BA, GRAS 12BE, GRAS 12BB are a cost-effective and high quality bridge between CCLD sensors and data acquisition systems which don’t have integrated CCLD capability. These units can be deployed individually and/or multiple units can be used together to achieve the required channel count.
