  • Page 15: System Overview

    SYSTEM OVERVIEW Scope This Instruction Manual supplies details needed to install, startup, operate, and maintain the OCX 8800. Signal conditioning electronics outputs a digital signal representing oxygen (O ) and combustibles (COe) values. This information, plus additional details, can be accessed with the 375 Field communicator or Emerson AMS software.
  • Page 16 IM-106-880, Rev 2.1 OCX 8800 April 2017 The OCX 8800 measures net oxygen concentration in the presence of all the products of combustion, including water vapor. Therefore, it may be considered an analysis on a "wet" basis. In comparison with older methods, such as the portable apparatus, which provides an analysis on a "dry"...

    Model 375 Field Communicator - The handheld field communicator requires Device Description (DD) software specific to the OCX 8800. The DD software will be supplied with many Model 375 units, but can also be programmed into existing units at most Emerson service offices. Refer to Section 6, Field Communicator, for additional information.
  • Page 18 April 2017 System Operation Figure 1-2 shows the relationship between the components of the OCX 8800. The sensors and the electronics are contained in separate housings. The sensor housing and probe mounts to a duct or process wall so that the probe protrudes into the flue gas stream.
  • Page 19 It is important that printed circuit boards and integrated circuits are handled only when adequate antistatic precautions have been taken to prevent possible equipment damage. The OCX 8800 is designed for industrial application. Treat each component of the system with care to avoid physical damage. The probe may contain components made from ceramics, which are susceptible to shock when mishandled.
