DescriptionSeries 6800 for portable applications is a ready-to-run, high performance measurement system that is DC powered for mobile applications. All connections are front mounted for easy installation in tight places or on the go. 6800 systems come equipped with a conditioner, amplifier, filter and digitizer. Each channel has a front mounted connector specific to a measurement type: RJ-45 for 8-wire bridge transducers and BNC for voltage or ICP/IEPE inputs. Individual channels have a differential ±10V input and can digitize and record data to 16-bit resolution with upper and lower programmable alarm capability that is checked each time the output is digitized. Solutions are available for providing digital outputs based on these alarm conditions. Systems interface to a familiar Windows based Operator Workstation over USB where the included software, PI660, is used for setup, display and acquisition of measurement data. PI660 allows for acquisition and control of one or many 6800 systems and provides real time data display. Data can be displayed and recorded in any number of ways, creating a versatile system that can fit any application and can be easily expanded or customized, should test requirements change. Multiple systems can be combined for larger and/or distributed installations, made capable with an onboard, distributed sample clock bus. Programming and data transfer are over USB which provides high data transfer rates with low, predictable latency. It interfaces to the USB port provided on most PC computers, including laptops for ultimate portability. Data Redundancy is optionally available. A 2.5" HD (Model 6095) mounts on the USB controller board in each system and provides a redundant recording point for the DAS. In the unlikely event the Operator’s Workstation or DAS Software fails, data will continue to record and can be recovered from the system post test. The Operator’s Workstation (6800-PCCOWU-LT) is the primary control and data recording point for the Series 6800 DAS. The PCCOWU-LT is typically a laptop, connected to the USB port and runs PI660 Data Acquisition Software for system setup, calibration, display, recording, distribution and export.
