Pressure cascade monitoring for a sterile filling suite
Challenge
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 transmitters with buzzer were installed on every room-to-room boundary, with DPT30 relay versions on the airlocks. All transmitters send 4–20 mA to the BMS and, via a CloudWAY gateway, to CloudDASH360, where SMS and e-mail alarms are configured for each grade.
