MSA Safety A-ULTX-SENS-31-1-CC Ultima X Series Combustible Gas Sensor

MSA Safety Logo

The MSA Safety A-ULTX-SENS-31-1-CC is a high-performance replacement gas sensor designed for the industry-leading Ultima X Series of gas monitors. Specifically calibrated to detect Combustible Gases (including Natural Gas and Hydrogen) within a 0–100% LEL (Lower Explosive Limit) range, this catalytic-bead sensor provides rapid, accurate, and stable life-safety telemetry in demanding industrial environments. Housed in a rugged 316 Stainless Steel enclosure featuring fine threads and conformal coating for enhanced environmental protection, it is purpose-built for integration into explosion-proof (XP) Ultima X transmitter models (excluding IR configurations). As a critical component of hazardous gas detection systems, it ensures plant personnel and assets remain protected from highly volatile, explosive gas accumulation.
