CH4 methane sensor Gasboard-2501 Series

TDLASfor leak detectionfor the petrochemical industry

Gasboard-2501 methane sensor is high-performance gas sensor based on tunable laser absorption spectroscopy technology (TDLAS). Adopting a narrow-band tunable laser source, special gas chambers and optical path design, Gasboard-2501 TDLAS CH4 sensor has features of great stability, high precision, enhanced fast response, humidity interference-free, low maintenance and long lifetime. Gasboard-2501 series could measure CH4 up to 100%Vol, are designed for scenarios with harsh working conditions. Suitable applications include Oil & Gas industry, energy sector, landfill monitoring, LNG transportation, gas leak detection, emission quantification, etc. - Features • Narrow absorbing spectrum determines great selectivity to CH4 • Laser technology to ensure superior accuracy with low drift • Great anti-cross interference to other gases and high humidity • Fast response time • Low power consumption • Long lifetime over 10 years • ATEX & IECEx Ex ia IIC T4 Ga certified - Specifications • Principle: TDLAS • Measurement Gas: CH4 • Model: Gasboard-2501-05F; Gasboard-2501-100F • Measurement range: Gasboard-2501-05F:0~100%LEL (0~5%Vol); Gasboard-2501-100F:0~100%Vol • Accuracy: Gasboard-2501-05F:±5%LEL; Gasboard-2501-100F:±(0.25%Vol or 5% of reading, take whichever is greater) • Resolution: Gasboard-2501-05F:0.1%LEL; Gasboard-2501-100F:0.01%Vol • Response time: T90＜20s • Output: UART_TTL (3V) • Working Condition: -25~55℃, 0~98%RH (non-condensing) - • Storage Condition: -40℃~85℃, 0~98%RH (non-condensing) • Power Supply: 3.2~5.5V DC • Working Current: <30mA (@25℃, 3.3V DC) - • Dimension: Dia35mm*H57.5mm
