Yokogawa K9471UA Dust Filter for Oxygen Analyzer
Product Introduction
Manufactured by Yokogawa, the K9471UA is a specialized dust filter
designed for oxygen analyzers. It serves to safeguard the cell from
corrosive dust components and high - velocity dust in environments
like recovery boilers and cement kilns. With a focus on ensuring
proper gas replacement within the zirconia sensor (requiring a
sample gas flow rate of 1m/sec or more), this filter plays a
crucial role in maintaining the performance and longevity of oxygen
analyzers in industrial settings. It usually ships in 1 - 10
working days, providing a timely solution for equipment protection
needs.
Key Features
- Protective Function: Shields the oxygen analyzer cell from
corrosive dust components and high - velocity dust, especially
suitable for harsh environments such as recovery boilers and cement
kilns.
- Gas Replacement Support: Facilitates the replacement of gas inside
the zirconia sensor, with a requirement of a sample gas flow rate
of 1m/sec or more to ensure effective operation.
Specified Specifications
- Mesh size: 30 microns, enabling precise filtration.
- Material composition: SiC for the filter part and SUS316 (JIS) for
structural support, ensuring durability and resistance to
