Rosemount™ OCX8800Oxygen and Combustibles Transmitter

Continuous, accurate measurement for combustion processes

The Rosemount OCX8800 Oxygen and Combustibles Transmitter provides continuous, accuratemeasurement of combustion flue in a single, easy-to-install transmitter design. The patented Rosemountzirconia oxygen sensor coupled with a combustibles sensor using catalytic bead technology provide thebasis for measurement in flue gases with temperatures up to 2600 °F (1427 °C).

Overview

Proven performance and reliability■ Robust zirconia oxygen-sensing cell with catalytic platinized

beads increases cell lifetime in presence of sulfur and otherpoisoning agents.

■ Robust COe sensor features a large active surface area anddilution air for accurate readings even in reducingconditions.

■ Compact explosion-proof housings that are easy to mountdirectly to the process.

Adaptable to a range of processes

■ FOUNDATION™ Fieldbus and HART® communication protocoloptions allow technicians to view diagnostic and operationalinformation from the control room.

■ The local operator interface (LOI) enables localcommisioning and maintenance and permits visibility todiagnostics without additional tools.

■ Integral or remote-mounted electronics and auto-calibration options simplify routine maintenance tasks.

Product certifications

European Directive informationA copy of the EC Declaration of Conformity can be found at the end of the Quick Start Guide. The most recent revision of the ECDeclaration of Conformity can be found at Emerson.com/Rosemount.

Ordinary location certificationAs standard, the transmitter has been examined and tested to determine that the design meets the basic electrical, mechanical,and fire protection requirements by a nationally recognized test laboratory (NRTL) as accredited by the Federal Occupational Safetyand Health Administration (OSHA).

Installing equipment in North AmericaThe US National Electrical Code (NEC) and the Canadian Electrical Code (CEC) permit the use of Division marked equipment inZones and Zone marked equipment in Divisions. The markings must be suitable for the area classification, gas, and temperatureclass. This information is clearly defined in the respective codes.
