Caroline Y

OGI for SMART LDAR surveys


Caroline Y is SENSIA’s latest model of Optical Gas Imaging (OGI) for the detection of fugitive emissions of methane (CH4), SO2 and VOC’s leaks. It integrates a spectrally optimized high-resolution uncooled detector that detects the 90% of diffused gas emissions caused by leaks.

Featuring an integrated touch screen display, Caroline cameras run the software application RedLook embedded increasing the functionality and simplicity of the device.

Considerations related to the MDLR determination for the SENSIA OGI’s

  • Leak observation is done at distance short enough to ensure the leak resolvancy with various pixels
  • Characterization test conditions:

o    Background temperature controlled

o    Outlet Orifice Diameter= ¼’’

o    CH4 diluted with N2 (25% methane)

  • Gas Detection condition using High Sensitivity Mode

Innovative capabilities assembled under a single control software

Enhanced Mode

Redlook is capable of automatically coloring the gas to facilitate the identification. With SENSIA OGI cameras, you can scan broad sections of equipment rapidly and survey areas where traditional contact measurement tools cannot access.

Quantitative OGI

Placing the OGI on a tripod activates automatic quantification of gas leaks: fast, accurately and safely.



Caroline Y for LDAR Campaigns

Caroline Y has a new design, a 5-inch touch screen and runs under RedLook, the most powerful and intuitive software for gas visualization. This control and analysis software unfold the full potential of Caroline Y Optical Gas Imaging.

Caroline Y has the main international certifications in temperature, humidity, vibration, dust and water intrusion and hazardous environments.
