The Honeywell 2106B2310, also cataloged as the Sensepoint HT flammable sensor, operates as an ATEX‑rated detection element for combustible gas monitoring in high‑temperature industrial environments.
When integrated into Honeywell process control systems, the Sensepoint HT sensor aligns with:
Channel‑to‑channel isolation across multiple detection points.
FOUNDATION Fieldbus / Profibus PA connectivity via controller interface modules.
Cold junction compensation (CJC) applied in associated transmitter cards.
4‑20 mA HART loop protocol conversion from the sensor’s mV bridge output, ensuring compatibility with distributed control systems.
Frequently Asked Questions (FAQ)
Q: What is the minimum alarm threshold supported? A: The sensor supports a minimum alarm level of 5% LEL, configurable via the control card.
Q: How fast does the sensor respond to flammable gas presence? A: T60 response is less than 6 seconds, and T90 response is less than 10 seconds under rated conditions.
Q: What enclosure material is used? A: The sensor housing is constructed from 316 stainless steel for durability in harsh environments.
Field Installation Guidelines
Mount sensor using M20 threaded interface in designated detection zones.
Ensure wiring integrity for mV bridge output to controller input cards.
Maintain ambient humidity between 20–90% RH continuous, 10–99% RH intermittent.
Operate within pressure range 75–110 kPa to ensure accurate readings.
Ground stainless steel enclosure to plant earth for EMI suppression.
Verify alarm setpoints on control card after installation to match required LEL thresholds.
