1. Product Basic Positioning
This model is a **Sensepoint HT series high-temperature resistant catalytic combustion type combustible gas sensor probe** under Honeywell. It is specially designed for high-temperature hazardous working conditions, suitable for scenarios where conventional sensors cannot be applied, such as high-temperature furnaces, turbine casings, and high-temperature drying lines. It can be connected to Honeywell gas alarm controllers and third-party DCS/ESD safety systems for combustible gas leakage monitoring and interlock protection.

3. Core Functional Features
1. Special Adaptation for High-Temperature Scenarios**
Can be directly installed on high-temperature equipment points such as turbine shells, drying kilns, and the outer side of high-temperature chimneys without the need to add additional cooling sampling pipelines, simplifying the on-site installation structure.
2. Strong Anti-Toxic and Durable Design**
Uses Sieger anti-toxic catalytic bead elements, which do not fail in chemical plants and fuel oil areas with trace corrosive exhaust gas, reducing the maintenance cost of frequent consumable replacements.
3. Explosion-proof Safety and Reliability**
Full stainless steel explosion-proof housing, suitable for 1/2 class hazardous explosion-proof areas in petrochemical, oil and gas stations, and power plant boiler areas; can be paired with HIMA X-CPU31 safety CPU to connect ESD emergency stop interlock links.
4. Strong Network Compatibility**
Can be used in conjunction with Honeywell original gas controllers, or connected to ABB RTU560 remote control platform or general DCS systems to achieve centralized monitoring of all plant leakage data.
4. Typical Application Scenarios
– Power Industry: Flammable gas monitoring around gas turbine shells and boiler chimneys;
– Petrochemical Industry: Leakage detection in high-temperature reactors, drying production lines, and high-temperature oil and gas pipelines;
– Industrial Kilns: Gas leakage warning around the drying furnaces and heat treatment furnaces;
Can be paired with the previous ABB UV5627B-E vibration monitoring module to cover mechanical status of the unit and gas safety protection.
