In gas delivery pipelines, high flow velocity transports particulate matter through the sensing zone. As particles pass the probe, the sensor generates a low-level induced current containing essential concentration-related data. The PFA13 sensitively captures dynamic changes in the flow field’s electric charge and field intensity. Using a proprietary circuit and advanced algorithm, the system samples and processes signals at high speed—effectively filtering interference to extract valid particulate concentration data with high accuracy.

Application Fields
The PFA13 is widely used in various harsh industrial environments where particulate monitoring is required, including but not limited to:

· Catalytic cracking units and process gas pipelines in the petrochemical industry

· Coal gasification and coal-to-ethylene glycol units in the coal chemical industry

· Flue gas dust removal and process air systems in non-ferrous metal smelting

· Blast furnace gas and converter gas purification systems in the steel industry

· Other industrial gas pipelines requiring continuous and precise particulate concentration monitoring
