Methane is a colourless & odourless gas and is a main component of natural gas. Methane leakage, if goes undetected may result in a potential major hazard. The largest source of industrial emission of methane is from Oil and Gas industry. Hence methane gas detection plays a major role  in Oil & Gas industry.


Methane gas is present and can get accumulated at drilling sites, storage tanks or transmission pipelines. Undetected leak can create hazardous concentrations of combustible gases, putting equipment, facilities, and personnel at risk. Hence methane gas detection is critical for protecting people and property from these hazards. It’s vital to have detection equipment that can alert those nearby to dangerous levels of methane.


There are many factors to consider when selecting an appropriate methane gas sensor. Apart from accuracy, installation and working conditions, area classifications and functional safety also plays a critical role in choosing the best gas sensor for a particular application.


GasAlarm presents gas sensor from PolyXeta II series for continuous monitoring of methane gas. It’s a microprocessor based gas sensor with 4-20mA/RS 485 output signal. It can be supplied with LCD display with green or red backlight. The PolyXeta II methane gas sensor comes with SIL 2 approval for safety related applications and carries an IECEx hazardous area certification. It can also be supplied with a flameproof enclosure.


Continuous monitoring can help in early detection of methane leakage and prevent gas emissions in the atmosphere. For further details, please visit our website at: PolyXeta II methane gas sensor
