New analysers for hazardous locations
AMETEK Process Instruments has expanded its 993X series of gas analysers – including both 993X and 9933 models – with new explosion-proof enclosures certified for ATEX and IECEx Zone 1 hazardous locations. AMETEK says that the new design enables reliable analyser installation in applications where purge gas is unavailable or impractical, addressing a common challenge in remote and utility-limited facilities. The explosion-proof 993X enclosure is rated IP66 and NEMA 4X, allowing outdoor installation and operation in minimally temperature-controlled environments. By eliminating the need for a continuous inert purge gas supply, the design helps reduce installation complexity, operating costs, and overall system infrastructure requirements.
“Many customers rely on purge-protected analysers, but those systems are not practical in every Zone 1 location,” said Michael Gaura, senior product manager at AMETEK Process Instruments. “The explosion-proof 993X gives users a robust alternative that maintains measurement performance.”
The 993X series primarily uses ultraviolet (UV) spectroscopy to provide continuous measurement of sulphur compounds and other key components in natural gas and biomethane streams, including hydrogen sulphide, carbonyl sulphide, and methyl mercaptan. The analysers are also widely used in sulphur recovery and removal processes to measure sulphur-containing species such as sulphur dioxide and carbon disulphide, supporting process control, emissions compliance, and product quality. Other technologies can also be integrated to measure the concentrations of hydrogen and carbon dioxide in these end-user applications, when required.
