nvea - Version eSAM -Data Acquisition and Management Module
FromENVEA
Data acquisition and management module (logger & router) handling all parameters: gas analysers, dust monitors, meteorological and temperature sensors. The eSam DAHS ensures remote, bi-directional access and control of analyzers and the EMS via a WEB based interface. Furthermore, these data can be automatically and wireless transmitted to a central server, equipped with the XR® software suite, able to handle thousands of AQMS stations in a town, city or region.

Data Acquisition
- Acquisition of instantaneous measurements at a configurable frequency ranging from 5 seconds to 24 hours
- Management of the metrological context: analysers’ parameters and internal failures, technical measurements, external signals (door opened, flow, etc.)
- Controls of lower and higher validity limits, sensitivity threshold, immobility, slope and follow-up of peak episodes
Automatic Validation
- Automatic validation of the data with the XR software
- Association of a quality code with each value
- Evaluation of quality indicators for each data value: min, max, standard deviation, number
of over-thresholds, availability ratio - Prevalidation of the data according of the metrological context
Calibration
- Automatic management of calibration sessions: 5 span points
- Ability to adapt the linearization parameters according to calibration results
- Control of absolute, relative drifts, drifts between span points, standard deviation drifts
- Storage of all the information related to the calibration
