Probe Failure in Fermenter
•A probe is used in a fermenter to detect various process values to ensure an effective fermentation process. The probe is calibrated externally and then mounted in the fermentation vessel.
•SAM GUARD detected a problem with dissolved oxygen probe which delivered false values.
•An alert was generated on 08/02 when there was change in the behavior of the oxygen profile.
If left undetected, incorrect oxygen values could affect the quality of the fermentation.
The probe was then replaced with a redundant probe to regulate the oxygen flow.
Product loss was prevented.
