Logging Systems
Logging and sensor interfaces for the MET system are provided by dedicated loggers, including an AEC 6612 Rev B computer and CSI CR1000 and CR3000 data-loggers.
Three data-loggers are employed to provide logging and control to the MET system sensors.
The Digital Logging Unit computer (DLU) is an AEC 6612 Rev B industrial computer running Linux, on which the NOAA BATSTORE software is employed to log the BAT probe data output, as well as serial data streams from the Li7500 and the RT3003 INS/DGPS. These streams provde the basic data required for 3D wind and eddy covariance calculations.
Additional serial data streams are also logged on the DLU for redundancy. These include: Picarro G2301m gas analyser, Riegl LD90-3300HR laser altimeter, and data transferred from the MET System's CR1000 and CR3000 dataloggers and the Central Services Module.
The MET-CR1 and MET-CR3 dataloggers are CSI CR1000 and CR3000 dataloggers respectively and support logging and control functions within the MET system.
Unlike the MET-DLU logging computer above, these units are also able to measure analogue channels, and support numerous sensors across the MET system. They also have analogue and digital outputs and are used to control various devices within the system.
They are monitored and controlled through flight using Loggernet RTMC software running on the Central Services Module's Control and Display Computer (CDC).
Please refer to the manufactures datasheets for detailed specifications and contact us for further information on our specific installations.
These logging systems are embedded in the ECO-Dimona's MET System (part of the EF19B sensor package).
We have 1 of each of these logging systems available.
