GE Aurora Trace Moisture Analyzer User’s Manual

Below you will find brief information for Moisture Analyzer Aurora Trace. The Aurora Trace is a moisture analyzer that uses a tunable diode laser which it scans across a narrow band in the near infra-red spectrum. This technology produces very fast response to changes in moisture concentration. The system is very reliable as it does not use any sensor that comes in contact with the process gas. The device provides direct readout in lbs/mmscf, mg/m3 or ppm, and reads process pressure dewpoint (with user programmable constant or live auxiliary input for process pressure). It is equipped with a display and a user interface which features magnetic induction keys, enabling it to be configured and programmed in a hazardous area without opening the increased-safety enclosure.

Frequently asked questions

The Aurora Trace uses a tunable diode laser which it scans across a narrow band in the near infra-red spectrum. This technology produces very fast response to changes in moisture concentration. The system is very reliable as it does not use any sensor that comes in contact with the process gas.

The Aurora Trace can display moisture in mole ratio (ppmv or ppbv), dewpoint temperature (°C or F), mass/volume (lbs/mmscf or mg/m3) and pressure dewpoint.

The Aurora Trace can communicate using three programmable analog output (0/4-20 mA) signals, RS-232 or RS-485 with Modbus and optional Foundation Fieldbus.
