ABB NGC8206 Natural gas chromatograph Operator interface

Sample conditioning system

The integral stream selector for the NGC8206 allows sampling

up to four (4) different natural gas streams. Up to two of these

sample streams can be designated as the “calibration/

validation sample”. Optional sample conditioning modules are

available to address natural gas streams that need additional

filtering and “speed loops” to reduce sample transport lag times.

Operator interface

Functional setup and operation of the NGC8206

is accomplished by using a graphical user’s interface software

package called PCCU 32 (supplied with each unit) operating on

a laptop PC in a Microsoft® Windows® environment. The

“Windows®” utilities, combined with software designed

specifically for the NGC8206, provide a powerful tool for

operations, diagnostics, and downstream data handling.

The PC can be directly connected to the NGC8206 via an

RS-232, USB, or Ethernet connection, or indirectly by remote

telemetry (phone modem, radio, cell phone, satellite, etc.).

The user is prompted through push-buttons, drop-down

boxes, wizards, and dialog boxes for setup, operations, data

collection and monitoring.

In addition, the unit has an optional ¼ VGA interactive display

screen allowing the user access to basic analysis data. The

user can also accomplish most of the “operator” functions

from the front panel display with out the use of a laptop PC.

The “Run-Hold-Calibrate” functions can be done via a magnet

interface through the explosion proof glass in the display.
