The (sintered metal filter media) gas sensor housing prevents the flame from transferring to a different area of a device by cooling or quenching a flame front or by dampening a combustion wave. It is designed to absorb and dissipate the heat of a flame for specific operating and flow conditions. Integrating HENGKO's sintered metal media provides high strength and durability allowing these critical devices to perform precisely.


    Sintered porous metal materials media (such as the picture - porous metal cups) are a popular media choice because these highly engineered materials consist of a uniform, interconnected porosity that can be fabricated to allow precise gas flow control while providing a mechanically sound media to quench the flame front. Sintered porous metal provides cost effective solutions for high volume devices, especially for applications that require the prevention of a flame front in the event that an intense explosion occurs. Sintered porous metal media can also be formed into net shapes and easily joined to hardware to create unique assemblies.

    HENGKO manufacture gas sensor housing to customers' individual specifications. It is recommended that customers validate porous metal for use in their equipment in order to obtain proper approval in their target market.


    Gas sensor housing is typically designed to meet specific flows, pore sizes and density characteristics and can vary widely in size and shape. This allows greater flexibility in meeting constraints of custom designed devices.
