OCX8800 supports Foundation fieldbus communication

Emerson Process Management has enhanced its Rosemount Analytical OCX8800 oxygen and combustibles transmitter to offer functionality and reliability in coal-fired applications.

The company said the enhancements will help to improve burner efficiency and reduce nitrogen oxide (NOx) emissions.

Featuring oxygen and combustibles measurement capabilities in a single design, the OCX8800 utilises an improved sensor technology that reduces drift.

The transmitter also supports Foundation fieldbus communication.

Adaptable to any oxygen and combustibles installation, the enhanced OCX8800 is NEMA 4x rated for weather resistance, corrosion resistance and is rated as explosion-proof.

The device can be configured for general-purpose installations or it can be configured for hazardous area locations in which CSA/FM Class 1, Zone 1 ATEX II 2 G EExd and IECex ratings are required.

The software also includes new features that minimise COe (carbon monoxide equivalent) cell degradation for improved reliability with fewer calibrations.

For added flexibility, the OCX8800 supports Foundation fieldbus and Hart communications.

The transmitters are part of the Emerson range of intelligent, digital field devices that power the PlantWeb architecture.

Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the transmitters are integrated into the Plantweb digital plant architecture.

The OCX8800 is easy to install with no electronics box, probe cable or conduit, and features a universal power supply for automatic line-voltage selection.

Integral or remote-mounted electronics options are also available.
