Emerson’s chemiluminescence gas analyzer with new digital communication capabilities enables reliable monitoring of nitrogen oxides (NOx) emissions. The Rosemount XECLD Process Gas Analyzer leverages the digital architecture of the Rosemount X-STREAM Enhanced (XE) suite of continuous gas analyzers to offer a full range of web-based communication capabilities, including secure, remote connectivity without the installation of additional software. This simplifies access to analyzer health and actionable process information to help operators comply with environmental regulations. Designed for optimum reliability and low cost of ownership, the gas analyzer utilizes chemiluminescence measurement technology with a thermoelectrically cooled, solid-state detector assembly to ensure highly stable measurement performance and a longer operating life. In addition, the analyzer eliminates vacuum pumps often used in chemiluminescent instruments, significantly reducing a potential source of vibration.
