Overview

The Honeywell Sensepoint HT Flammable Sensor (Model 2106B2312) is engineered to detect combustible gases in high-temperature environments up to 150°C (302°F). Built with a rugged 316 stainless steel housing, it is certified for ATEX and IECEx hazardous area operation, making it ideal for turbine enclosures, drying ovens, and solvent-based coating systems.

Moreover, its catalytic pellistor sensing technology ensures accurate detection with alarm thresholds as low as 5% LEL. The sensor’s thermally matched beads enhance stability and minimize drift, even under fluctuating temperature conditions. In addition, its low power consumption and extended operating life—typically over five years—make it a cost-effective choice for continuous gas monitoring.

Technical Data

Typical Applications

• Turbine Enclosures: Monitors flammable gases in high-heat zones where standard sensors may fail.

• Drying Ovens: Used in solvent-based printing and coating systems to prevent fire hazards.

• Chemical Processing Plants: Ensures safety in areas with volatile organic compounds and elevated temperatures.

• Industrial Furnaces: Provides early warning in combustion zones with high thermal stress.

• OEM Equipment: Integrated into high-temperature machinery for continuous gas monitoring.

For instance, in solvent recovery systems, this sensor helps maintain safe operating conditions by detecting leaks before they reach dangerous levels. Therefore, it plays a critical role in fire prevention and regulatory compliance.

FAQ
