Yamatake Corporation Introduction
Model HGC303 - Heat Value Gas Chromatograph 1-3
1-2 : General
The model HGC303 is a gas chromatograph designed to analyze natural gas and is
able to transmit a process variable via a Fieldbus signal.
One can easily adjust configuration data and monitor values such as the heat value by
using the HGM.
The heat value monitoring system, which can be controlled from both the model
HGC303 and HGM, will substantially minimize time, cost and maintenance.
This chapter first describes the measuring system and structure of the model HGC303.
After that, the characteristics and the specifications of Fieldbus are described in detail.
First time users of the model HGC303 should read this chapter carefully and thor-
oughly.
~Note
*: This is not necessary if using the model HFA100. However, the model
HFA100 can only run on Windows 2000 / XP. If you are running an
operating system other than Windows 2000 / XP, purchase the National
Instruments Fieldbus-PC Interface.
