Continued Improvements of the Oxygen/Combustibles Transmitter Emerson continues to enhance the design of the Rosemount Analytical OCX product line through continuous innovation. Improvements to the combustibles sensor and software to enhance the reliability of these measurements are primary reasons that the OCX leads the industry. The new sensor design and software upgrades make the OCX 8800 even more dependable. 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...

OCX 8800 The OCX 8800 Transmitter is completely field-repairable The OCX 8800 is 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). The electronics can be attached to the sensor housing or separate to provide a convenient location for the electronics and operator interface for integral mounted installations....
