Teledyne GFD launches MethaSense range of methane detectors

Teledyne Gas & Flame Detection (Teledyne GFD) gas has launched its new MethaSense range of battery-powered methane detectors, comprising three models using cutting-edge NDIR (non-dispersive infrared) sensor technology for reliable and precise methane detection

MethaSense, designed for residential and commercial applications, is a compact, wireless natural gas detector with a range of 0-5 % volume, featuring accurate detection without false alarms, and immediate alerts through integrated audible and visual alarms. With progressive signal processing algorithms, MethaSense detects, alarms and monitors methane at concentrations as low as 10% of the lower explosive limit (LEL) for enhanced safety. Optional wireless (LoRaWAN) connectivity enables real-time gas detection visualisation, providing clear, actionable insights.

MethaSense XP is engineered for industrial environments where robust performance and reliability are essential. MethaSense XP’s rugged design and reliable detection capabilities ensure worker safety and operational continuity, especially in areas where maintenance access is limited.

It combines the same advanced NDIR sensor technology with enhanced durability and wireless communication options, including LoRaWAN, NB-IoT and Bluetooth. MethaSense XP again features audible and visual alarms, while its 10+ year battery autonomy and immunity to corrosion and saturation make the detector ideal for continuous safety monitoring in demanding conditions. With ATEX and IECEx certifications, MethaSense XP operates reliably in hazardous zones.

MethaSense Trace is a high-performance methane detector for LDAR (leak detection and repair) and utility applications, where accurate and autonomous methane monitoring is essential for regulatory compliance and environmental protection. A rugged build with IP67 ingress protection rating for outdoor use ensure uninterrupted performance in harsh conditions, reducing operational risks and maintenance costs.

With exceptional methane sensitivity, it provides 10× higher methane selectivity than previous-generation sensors, with a detection range that extends from 50 ppm to 100% volume for both low-emission environmental monitoring and high-concentration safety thresholds.

The detector delivers 24/7 methane emission monitoring, detection and quantification across large-scale industrial sites. By combining real-time sensing, cloud-based analytics and automated reporting, MethaSense Trace enables operators to detect, localise and measure methane emissions with precision. This not only helps reduce emissions but also ensures full compliance with new methane regulations.

“NDIR technology, as utilised by all three detectors in our new MethaSense series, offers high selectivity, fast response times and long-term reliability,” explained Régis Prevost, product line manager, Teledyne GFD. “Users benefit from natural gas detectors that provide a low-maintenance, cost-effective, versatile solution for continuous methane monitoring, supported by key features that include up to 10+ years of battery life, zero recalibration requirements, wireless connectivity options, and suitability for smart infrastructure and safety-critical environments.”
