Honeywell XNX-UTSE-RHCB1 Industrial Combustible Gas Transmitter

The XNX-UTSE-RHCB1 transmitter gives field operators total safety by continuously monitoring flammable gas risks in tough industrial plants.

Summary Overview

• Honeywell builds the XNX-UTSE-RHCB1 transmitter to detect flammable gases across hazardous petrochemical facilities.
• This strong device uses a catalytic bead sensor to track combustible gas leaks quickly and accurately.
• The solid 316 stainless steel housing stops harsh salt air corrosion in heavy offshore platform applications.
• Integrated relay controls activate local sirens or shut down equipment immediately during dangerous gas leaks.
• Operators change settings easily using local HART handheld tools without opening the heavy steel housing cover.

Core Technical Parameters

• Brand Identity: Honeywell manufactures this reliable safety unit for critical gas monitoring systems worldwide.
• Model Identifier: Plant engineers specify the industrial part number XNX-UTSE-RHCB1 for full site safety.
• Measurement Scale Range: The catalytic sensor monitors explosive gas levels accurately from 0 to 100% LEL concentration.
• Response Time Speed: The internal sensing circuit triggers alert signals in less than 15 seconds during tests.
• Signal Resolution Output: Digital processing circuits deliver precise gas measurement readings down to 1% LEL resolution continuously.
• Full Scale Linearity: The calibrated sensor tracks gas levels with fine linear accuracy within ±3% LEL limits.
• Operating Temperature Range: Internal components work perfectly in extreme weather ranging from -40°C up to +65°C.
• Environmental Immunity: Specialized internal coating layers protect sensor electronics against heavy dust and high humidity.
• Interference Resistance: Advanced catalytic elements ignore common silicone vapors and reduce poison risks from field chemicals.
• Instrument Physical Weight: The thick stainless steel casing weighs approximately 6.8 kg (15 lbs) for stability.
