Description
The Honeywell KTTBA002 500kW Long Sensing Tube VMU is a sensing tube designed to transmit pressure signals within gas burner control assemblies. It is used with VMU 500kW venturi mixing units, where it connects the venturi section to the gas valve regulator for accurate monitoring of pressure differentials. This component plays an vital role in maintaining the correct air-to-gas ratio during combustion, supporting stable burner operation in HVAC systems. It is commonly fitted in commercial boilers and industrial heating equipment where consistent and controlled performance is required.
