The Sensi+ NG is a wall-mounted, laser-based analyzer for continuous real-time monitoring of H₂S, H₂O, O₂, and CO₂ in natural gas streams, designed for custody transfer, tariff compliance, and process monitoring. It uses ABB's Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) technology to deliver high accuracy, low cross-interference, and fast response times with a measurement update rate of 1.5 seconds. The instrument features a 7-inch local HMI, remote web GUI access, AnalyzerExpert™ self-diagnostics, and requires no consumables. It is certified for Class I, Division 1, Groups B, C, D T6 and Class I, Zone 1, AEx/Ex db IIB + H2 T6 Gb hazardous areas. Dimensions are 43.2 cm × 52.5 cm × 39.8 cm (16.9 in × 20.6 in × 15.4 in), with a weight of 50 kg (110 lb).
Sensi+, GLA533-NG model, detects simultaneously multiple gas contaminants in natural gas. It provides continuous measurements of H2S, H2O and CO2 for custody transfer, tariff compliance, and process monitoring.
A single, compact analyzer using ABB’s proven laser-based technology providing accurate measurement and facilitating fast response time for quick actions to process upsets.
The next generation single analyzer solution for multiple natural gas contaminants
The Sensi+ GLA533-NG model is specifically designed for natural gas contaminant monitoring by targeting H2S, H2O and CO2. Real-time monitoring of contaminant levels allows triggering of threshold alarms to redirect contaminated streams that would otherwise compromise safety and operational yield.
Sensi+ offers a simple and comprehensive user interface with AnalyzerExpert™ features for increased information and user experience that provide expert actions and insights directly from your device.
For over 15 years, ABB’s Integrated Cavity Output Spectroscopy (ICOS) laser absorption technology has been at the core of the world’s most reliable gas analyzers used for applications requiring highest overall performance. Advanced spectroscopic analyses provide highest accuracy, precision, sensitivity, and reliability.
