Sensi+™: Natural gas analyzer

Sensi+, GLA533-NG model, is a single, compact natural gas analyzer that detects simultaneously multiple natural gas contaminants in real-time in complex and time-varying natural gas streams.

This natural gas contaminants analyzer is based on a unique tunable diode laser (TDL) technology known as Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS™).

It provides continuous measurements of Hydrogen sulfide (H₂S), carbon dioxide (CO₂), and water (H₂O) which represent both a safety and a pipeline integrity risk.

Sensi+ natural gas technical analysis provides accurate measurement and facilitates fast response time for quick actions to process upsets.

Sensi+ is not only an essential tool for natural gas measurement for custody transfer, tariff compliance, and process monitoring but it also protects natural gas pipelines, storage facilities, and other mission-critical assets.

Designed to monitor natural gas contaminants

Sensi+ GLA533-NG model is a state-of-the-art gas analyzer designed to monitor natural gas contaminants such as H2S, H2O, and CO2.

Providing real-time monitoring of contaminant levels, Sensi+ gas measurement helps ensure safety and operational efficiency by triggering threshold alarms and redirecting contaminated streams. With its simple and user-friendly interface, Sensi+ offers AnalyzerExpert™ features that provide expert insights and actions directly from the device to perform natural gas technical analysis.

ABB's Integrated Cavity Output Spectroscopy (ICOS) laser absorption technology has been used for over 15 years in the world's most reliable gas analyzers, providing advanced spectroscopic analyses that offer unparalleled accuracy, precision, sensitivity, and reliability compared to other TDL analyzers.

One single analyzer for multiple natural gas contaminants
Fast response time for fast action on process upset
Accurate and reliable measurement for confident gas network operation
Ease of use, no consumable, low maintenance

Advantages of OA-ICOS technology

  • Fast response time to variations and quick refreshment rate on gas measurement
  • Minimizes cross-interferences using high-resolution diode laser absorption technology, low gas pressure, and data analytics
  • Reduced cost of ownership: The sample is directly measured without conditioning and the design reduces the use of consumables
  • Low sample flow, lowering the environmental impact and financial loss due to venting of natural gas
  • No need for periodic calibration
  • Internal performance metrics for asset health monitoring

What is the importance of measuring contaminants in natural gas and biogas (biomethane)?

Measuring contaminants in natural gas is crucial to prevent internal corrosion in the gas infrastructure such as pipelines and storage facilities.

Natural gas technical analysis allows to find high concentrations of target gas contaminants that can cause damage to mission-critical assets, which is why custody transfer mandates require the measurement of these gases.

Moreover, monitoring specific contaminants is mandatory for regulatory compliance and tariff adherence. With Sensi+ gas analyzer, you can measure three natural gas contaminants simultaneously and continuously using a single device.

Thoughtfully designed with the user in mind

Sensi+, the single, compact natural gas analyzer based on one technology, multiplexed laser absorption spectroscopy, brings all the advantages of laser technology, saves space, and removes the need for multiple analyzers. It also simplifies deployment, operation, and service without compromising performance.

Easy installation and commissioning for hazardous areas

With the flame-proof and dual-seal design, the hazardous area-compliant gas analyzer necessitates only a simple wallmount installation and process tie-in with no complex purging system.

Needing no field calibration, a simple validation in the field can be done and the gas analyzer is ready to deliver fast and reliable measurements. ABB Image-5Smaller

Intuitive and insightful user interface on a modern software platform

The Sensi+ natural gas analyzer provides state-of-the-art user interfaces both on local and remote access for quick and in-depth information.

Local Human-Machine Interface (HMI)
Sensi+ is equipped with a 7-inch screen, three informational LEDs, and a gesture control system.

The local HMI provides multiple views for detailed information:

    • Gas measurement screen
    • Alarms screen
    • Diagnostics and advanced diagnostics
    • System information


Gesture Control
The local HMI is a read-only user interface (UI) and navigation is made through a gesture controller. The user can navigate through the multiple software pages by passing hand in front of the Gesture detector below the screen.

Remote HMI

The remote HMI is a HTML based UI that provides in depth information and configuration without the need of proprietary software. The remote HMI provides multiple access and menus such as:

  • Gas measurement  screen
  • Settings and configurations of gas parameters, physical interfaces, and general parameters
  • Alarms display, acknowledgment, and information
  • Process events
  • Reports and export of historical data
  • Systems information
