Dedicated IR sensor for reliable methane detection
The OLCT 100 XPIR (explosion-proof IR) fixed-gas detector (photo) is a new infrared (IR) sensor that brings the advantages of stable and reliable methane-detection measurements to the industrial, utility and laboratory markets. 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 device offers a long lifespan, even with the presence of background gas, to deliver 100% lower-explosive-limit (LEL) methane detection. The IR methane sensors deploy two IR wavelengths: one active wavelength for gas absorption and one providing a reference wavelength to compensate for the impact of temperature and humidity. Because IR sensors do not require O2 to operate, these sensors are also suitable for use in 0–100 vol.% methane-gas environments. The ATEX-approved OLCT 100 XPIR comes with 4–20-mA output.
