Reliable oxygen and combustibles measurements in a single, easy-to-install transmitter design

Reliable oxygen and combustibles measurements in a single, easy-to-install transmitter design

With its rugged design, stable sensor, electronics and software package, the OCX 8800 is the most dependable oxygen/combustibles transmitter on the market. The power of this rugged and reliable design coupled with the inherent advantages of FOUNDATION™ fieldbus makes the OCX 8800 unmatched in overall performance. The ability to get real-time diagnostic information as well as the measurement variables over the fieldbus data highway makes the use of this analytical device even easier. For traditional installations, two separate 4-20 mA signals are used as outputs for this transmitter and are used for the oxygen measurement and combustibles measurement. They are fully field-scalable to each processes requirement. If the fieldbus option is chosen, all information is transmitted via the fieldbus H1 data highway over a single twisted pair of wires, thus reducing installation costs. The device can be configured for general purpose installations or it can be configured for hazardous area locations. The hazardous area ratings are CSA/FM Class 1, Zone 1 for NorthAmerica and ATEX II 2 G Exd for the European community and IECEx for all other world areas.

The time-tested zirconium oxide sensor is the basis for the oxygen measurement. This, coupled with the new combustibles sensor, can detect oxygen and combustibles concentrations in flue gases with temperatures up to 2600°F (1427°C). Typical applications include: refinery process heaters; power and utility boilers; petrochemical reactor furnaces; small package hot water and steam boilers; and waste fuel boilers & incinerators.

The OCX 8800 is also fully field-repairable. The probe’s design provides convenient access to internal probe components and electronics so technicians can service the unit in-house. The sensing cell and heater/thermocouple are fully field-replaceable. We offer sample probes in different materials and lengths up to 9 feet for flue gas temperatures up to 2600°F (1427°C).
