Methane leakage poses a significant safety risk in the operation of natural gas transmission and distribution systems, especially at critical points including pressure regulating stations, valve chambers, and metering stations. In the event of methane leak, there is a high potential risk of explosion, threatening personnel safety, equipment integrity, and the surrounding environment.
In order to achieve earlier and more reliable methane leakage warning, Cubic, a leading manufacturer of gas sensors and gas analyzers, has launched the high-performance Gasboard-2501 methane sensor based on TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, which is well-suited for fixed-point monitoring applications and enables real-time methane detection and rapid warning in critical areas.
Adopting a narrow-band tunable laser source, special gas chambers and optical path design, Gasboard-2501 offers superior methane gas selectivity and strong resistance to interference from water vapor and other gases, even under complex background conditions or high humidity, guaranteeing highly accurate and stable measurements. It achieves high accuracy of ±5%LEL across the measurement range of 0-100%LEL and operating temperature range of -25°C~+55°C.
Gasboard-2501 delivers fast response times, capturing fluctuations in methane concentration, which allows operators to take prompt action during the early stages of a leak. With inherent stability of laser-based detection, the sensor provides long-term operation without significant drift, with a long life exceeding ten years, significantly reducing the need for maintenance and recalibration. Engineered for low power consumption, Gasboard-2501 is suitable for deployment in continuous, long-term industrial monitoring.
To ensure safe deployment in hazardous zones, Cubic Gasboard-2501 is ATEX and IECEx Ex ia IIC T4 Ga certified, featuring an intrinsic safety design that meets the stringent safety standards of industrial environments and can be employed within fence line. Its robust structure allows reliable operation in pressure regulating stations, metering facilities, regulator cabinets, valve pits, underground valve rooms, as well as gas storage sites, LNG terminals, and distribution stations, covering all high-risk, high-priority areas along the gas infrastructure.
With outstanding accuracy, fast response, superior anti-cross interference, low power consumption, and long lifetime, Cubic Gasboard-2501 TDLAS methane sensor can be seamlessly integrated into stationary gas detection systems. It helps operators to build an intelligent, networked monitoring infrastructure across critical points of the gas pipeline network, allowing real-time identification of potential methane leaks, enhancing personnel safety, minimizing economic loss, and supporting long-term sustainable operation.
