Overview
The Honeywell 2106B2312 Sensepoint HT is a high-temperature flammable gas sensor designed for hazardous areas. Its robust 316 stainless steel housing ensures durability in extreme environments. Certified for ATEX and IECEx, this sensor reliably detects flammable gases in industrial settings such as turbine enclosures, drying ovens, and solvent-based coating systems. The sensor provides fast response times (T60 < 6s, T90 < 10s) and configurable detection ranges from 0–20% LEL to 0–100% LEL, depending on the controller used. With IP66 protection and a wide operating temperature range of –55°C to +150°C, it ensures safety and compliance even in harsh conditions.
