Abstract
A solid powder trapping system for filtering out solid powder from a mixture of gaseous reactants that also includes a device capable of determining the degree of powder accumulation inside the trap. The powder trapping system uses a powder trap to catch the solid powder within the gaseous mixture. A magnetic flux sensor is also installed inside the trap for measuring a magnetic flux whose strength depends on the amount of solid powder inside the trap. The magnetic flux sensor is connected to a display device so that reading from the display device reflects the amount of solid powder accumulated inside the powder trap.
