Teledyne Gas and Flame Detection is introducing a new infrared (IR) sensor for its class-leading OLCT 100 XPIR (explosion-proof IR) fixed gas detector that will bring the advantages of stable and reliable methane detection measurements to the industrial, utility and laboratory markets.

Methane poses threats due to its explosive mixtures and potential harm to humans and the environment. Sectors are increasing their methane detection capabilities due to increased demand from industrial, utility, and laboratory markets.

Investing in IR technology offers an economic advantage, especially in environments with methane-containing gases.

IR technology outperforms catalytic oxidation, which requires frequent sensor replacements and calibration. This is due to the need for enhanced measurement stability and lower alarm thresholds.

To meet market demand for a more robust and cost-effective solution, Teledyne GFD is releasing a new IR sensor dedicated to methane detection.

Designed for the company's highly popular OLCT 100 XPIR fixed gas detector, the IR sensor ensures measurement stability and is impervious to catalytic poisons.

Moreover, the solution offers a long lifespan, even with the presence of background gas, to deliver 100 per cent LEL methane detection.

To explain the principle of operation, IR methane sensors deploy two wavelengths of IR energy: one active wavelength for gas absorption and one providing a reference wavelength to compensate for the impact of temperature and humidity. As IR sensors do not require oxygen to operate, these sensors are also suitable for use in 0-100 per cent by volume methane gas environments.

The ATEX-approved OLCT 100 XPIR, a proven performer in the detection of refrigerant, CO2 and combustible gases, comes with 4-20mA output ensuring safe and reliable operation.

"Our new OLCT 100 XPIR with IR methane sensor ensures the protection of workers, assets and the environment from the potentially damaging and harmful effects of methane," explains Régis Prévost, Product Line Manager at Teledyne Gas and Flame Detection. "Our expert design and development team is constantly looking at ways to meet the demands of customers, helping them overcome real market challenges. With this new product they now have access to a stable, reliable and cost-effective way of performing methane detection measurements."
