Data acquisition and management system

• Air quality monitoring stations: fixed or mobile

• The eSAM data acquisition module is available on:

Rack 19”, 3U Frame

• • WINDOWS or LINUX OS
  • Standard configuration: 6 serials ports, 2 Ethernet ports, 6 USB ports
  • Option: additionnal I/O, 6 or 8 analog input, 6 DI + 6 relay, 8 additional RS 232

Desktop Computer

• • WINDOWS OS
  • Standard configuration: 8 RS 232, 1 Ethernet
  • Option: additionnal I/O, 6 or 8 analog input, 6 DI + 6 relay, 8 additional RS 232

Fanless industrial chassis

• Linux OS
• Standard configuration: 4 Serial ports (3 RS232, 1 RS232/485), 2 Ethernet ports, 4 USB Ports
• Option: additionnal I/O, 6 or 8 analog input, 6 DI + 6 relay, 8 additional RS 232

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
