The MSA Safety A-ULTX-SENS-58-3-0 is a high-performance replacement infrared (IR) gas sensor designed for the industry-leading Ultima XIR Series of gas monitors. Specifically calibrated to detect Combustible Gas (specifically Methane) within a 0–100% LEL (Lower Explosive Limit) range with an ATEX-compliant 4.4% CH4 baseline, this advanced non-dispersive infrared (NDIR) sensor provides rapid, accurate, and stable life-safety telemetry in demanding industrial environments. Housed in a rugged 316 Stainless Steel enclosure featuring M25 metric threads, it is purpose-built for integration into ATEX-certified explosion-proof (XP) Ultima XIR transmitter models. Unlike catalytic bead sensors, this IR technology operates effectively in oxygen-depleted environments and cannot be poisoned by silicones or heavy metals, ensuring plant personnel and assets remain consistently protected from highly volatile, explosive methane accumulation.
