SYSTEM OVERVIEW Scope
This Instruction Manual supplies details needed to install, startup, operate,
and maintain the OCX 8800. Signal conditioning electronics outputs separate
4-20 mA signals representing oxygen (O
2
) and combustibles (COe) values.
This information, plus additional details, can be accessed with the HART
Model 275/375 handheld communicator or Rosemount Analytical AMS
software.
System Description
The OCX 8800 is designed to measure oxygen and combustible
concentrations in flue gas temperatures up to 2600°F (1427°C). Electrical
connections, power and communications are made through two 3/4 NPT ports
in the flameproof electronics enclosure using fittings and cables provided by
the customer. Cable installation must meet NEC, IEC and/or other applicable
national or local codes for Class I, Zone 1, Group IIB +H2 T3/T6 permanently
mounted equipment. The transmitter is close coupled to the process and
requires minimal sample conditioning requirements.
