Pressure cascade monitoring for a sterile filling suite
Example projectChallenge
A sterile filling suite with Grade B, C and D areas relied on manual magnehelic readings twice per shift. Pressure reversals during material transfer went unnoticed until the next round, and paper records were hard to review for audits.
Solution
DPT20 differential pressure transmitters were installed on the room-to-room boundaries – buzzer versions where staff need a local alarm, 4–20 mA versions where the value goes to the BMS – with DPT30 relay versions on the airlocks. The BMS records the pressure trend for each grade.
