Description
The Laars Heating Systems E2340000 Flue Gas Sensor is a 1/4 inch NPT duplex temperature-sensing unit that measures exhaust gas temperature within the flue pathway. It is used in boiler equipment, where it monitors stack temperature to provide input for combustion management and safety response in HVAC systems. This sensor features a dual-layer configuration that offers redundant sensing capability for consistent readings under varying operating conditions. Mounted along the exhaust or flue section, it tracks heat levels in discharged gases to assist in maintaining proper combustion conditions and preventing excessive temperature rise.
