Main point
A rising pressure difference is a reason to review operating conditions, not an automatic instruction to increase cleaning pressure. Compare readings taken under comparable production loads before deciding what changed.
Information to record
Record the instrument identification, measurement points, production rate, fan setting and cleaning state with each reading. Mark filter changes, shutdowns and process changes on the same timeline. An isolated reading without its operating context is difficult to interpret.
Review and acceptance
Ask the equipment supplier to compare the trend with the collector's documented operating range. Separate checks of the measuring arrangement from checks of filtration and cleaning. Agree the evidence needed to confirm a correction, including a repeat reading under the original comparison conditions.
FAQ: Is a single high reading enough to diagnose blocked bags?
No. Confirm the reading and operating context, then compare other observations before assigning a cause.
FAQ: Should every collector use the same alarm value?
Use the applicable equipment and project requirements; a generic number does not establish the correct alarm for another installation.
