ABB NGC8106 Natural gas chromatograph Historical data

Historical data

The NGC8106 is designed to retain historical data. This data

can be used for audit trails, maintenance, and troubleshooting

to verify transmitter operation over time and provide a limited

data backup for communication link reliability.

The user is allowed to configure the period of the data

retained by the NGC8106 via the Operator Interface. The

default1 memory configuration provides the most recent 480

analysis cycles containing:

Stream averages for the (default1) 840 last hours, 35 last

days and the most recent last month analyses. Operational

parameters for the (default1) last 480 cycles (Diagnostics

Report): Audit logs (default1); Data retained by the NGC8106

can be collected via a remote communication link or by the laptop

PC local operator interface PCCU.

Installation dimensions

Specifications

– Designed for gas streams with the following characteristics:

– Clean is defined as having no particles larger than 1

micron and no more than 1 milligram of solids per cubic

meter of gas

– Dry is defined as no more than 7 psi of water per million

cubic feet of gas

– Dry is also defined as having less than 0.1 ppm of liquid

at the coldest ambient condition expected at the coldest

point in the system (the liquid can be water, oil, synthetic

lubricant, glycol, condensed sample, or any other nonvapor contaminate)

– Stable gas is defined as a vapor containing less than 0.1 ppm

of liquid when the vapor is cooled to 10°C below the coldest

ambient temperature possible at any point in the system

– Single stream capability. Manual calibration required
