Explosion proof analysis.

AMETEK Process Instruments has expanded its 993X series of gas analyzers – including both 993X and 9933 models - with new explosion proof (Ex d) enclosures certified for ATEX and IECEx Zone 1 hazardous locations. The new design enables reliable analyzer 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 analyzers, 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 sulfur compounds and other key components in natural gas and biomethane streams, including hydrogen sulfide, carbonyl sulfide, and methyl mercaptan. The analyzers are also widely used in sulfur recovery and removal processes to measure sulfur-containing species such as sulfur dioxide and carbon disulfide, 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.

With the addition of explosion proof certifications, the 993X series offers greater flexibility for operators designing analyzer shelters and hazardous area installations across oil and gas production, processing, and renewable gas applications.

Moisture analyser line expanded.

AMETEK Process Instruments has introduced two new additions to its next-generation line of quartz crystal microbalance (QCM) moisture analysers, the 3050-SLR and 3050-DO. Building on the advanced features of the recently introduced 3050-OLV, these versions are designed to provide precise, reliable measurements in the most demanding industrial applications.

The 3050-SLR and 3050-DO are purpose-built for ultra-low moisture applications. To ensure accurate, stable results with minimal maintenance, both models incorporate an integrated Zero Module and an advanced purge system. Together, these features reduce baseline noise and drift by minimising the effects of ambient humidity, electronic noise, vibration, and other environmental factors.

As with the 3050-OLV, operators can monitor data and alarms in real time using a user-friendly optical keypad and integrated display without requiring a hot-work permit. Built-in NIST-traceable self-verification supports confidence in analyser performance while reducing the need for external validation and downtime.

“The launch of the 3050-SLR and 3050-DO reinforces our commitment to delivering robust solutions for the most demanding moisture measurement applications,” said Ryan Cumpston, gas analysis product manager. “These versions combine the latest innovations in QCM technology with unmatched performance for ultra-low moisture detection, setting a new standard for accuracy and reliability in the industry.”

The 3050-SLR and 3050-DO expand the 3050 moisture analyzer portfolio, giving industrial customers new options for stable, ultra-low moisture measurement backed by the latest QCM innovations.
