Cubic Miniature NDIR Methane Sensor For Oil and Gas Tankers in Marine Transportation Industry

With the continuous growth of global natural gas demand, the proportion of clean energy such as liquefied natural gas (LNG) and compressed natural gas (CNG) in international transportation continues to increase. Specially, as an important tool for carrying clean energy sources in offshore transportation, oil and gas tankers take important responsibilities to ensure the stable transportation of natural gas.

However, with the complexity of power systems and fuel structures, oil and gas tankers have put forward higher requirements for real-time monitoring of flammable gases including methane. Especially in areas such as fuel tanks, valve rooms, and closed pipelines, even small leaks may cause serious accidents. Therefore, it is very important to achieve stable and high-precision methane detection under conditions of limited space and complex environments.

To provide accurate and stable detection for methane leakage, Cubic, as a leading manufacturer of gas sensors and gas analyzers, has leveraged its mature NDIR technology to specially develop standard industrial 4-seires miniature NDIR methane sensor SJH series, which can be integrated into a variety of marine combustible gas detectors. Cubic SJH series achieves accurate measurement of methane in the range up to 100% vol. With dual-beam design and Cubic matrix calibration process, Cubic SJH series effectively reduces the error caused by environmental drift, and improves the overall measurement accuracy.

Moreover, its miniaturized structure can be easily integrated in various types of marine detectors, and can be flexibly deployed even when the internal space of the equipment is extremely compact. Cubic SJH series also supports both voltage and serial port output, which is convenient for integrated communication with the data processing module in the gas detector to achieve real-time data feedback and alarm linkage functions.

In the high humidity, high salt spray, and high vibration environment unique to ships, Cubic SJH series demonstrates excellent industrial reliability. It adopts corrosion-resistant housing and sealing technology, and build-in temperature & humidity compensation algorithm, which can maintain accurate output within the operating temperature range of -40℃ to +70℃ and 0-95%Rh, ensuring the continuous operation of the detection equipment under various extreme working conditions.

In addition, its mature and stable product features provide highly reliable core component support for system integrators and detector manufacturers, helping equipment meet the safety and compliance requirements of the global shipping market.

Key product features highlight:

• Dual-beam NDIR technology

• Fast response time T90<25s

• Linearization and factory calibration for accurate digital output

• Matrix calibration to ensure high accuracy over full temperature

• Embedded temperature and humidity compensation

• Innovative high humidity alert mechanism

• Long lifespan over 10 years

• Ex-proof grade Ex ia II C T4 Ga

With these advantages, Cubic miniature NDIR sensor SJH series can be widely used in the field of methane detection in oil and gas tankers. In the future, Cubic will continue technological innovation to create a more efficient, safe and intelligent gas detection sensing solution for marine transportation industry.
