STABLE AND RELIABLE METHANE DETECTION MEASUREMENTS
eledyne Gas and Flame Detection has introduced 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 many threats. Not only does it form potentially explosive mixtures with air, but it can also prove harmful to both humans and the environment. For these reasons, many sectors are keen to step up their methane detection capabilities. Increasing demand from the industrial, utility and laboratory markets stems from the need for enhanced measurement stability, aligning with the trend of lower alarm thresholds.

The economic advantage of investing in IR technology becomes apparent when considering factors such as total cost of ownership (TCO), especially in environments when gases such as methane are present. In such applications, IR technology outperforms catalytic oxidation, a process that typically requires recurring sensor replacements and frequent calibration. To meet market demand fora 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% 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.” As a final point of note, the same IR sensor technology is available with Teledyne Gas and Flame Detection’s 700 series of fixed gas detectors. These advanced instruments display sensor status information on a built-in alphanumeric LED screen.
