Let’s start the week with a nice “how-to” video, How to Configure the Rosemount 3051S Plugged Impulse Line Diagnostic. Emerson’s Megan Wiens shows how to configure the Rosemount 3051S Plugged Impulse Line Diagnostic to help prevent this plugging condition which can lead to reduced measurement accuracy, plant efficiency, and product quality. Megan opens the video […]

Statistical Process Control (SPC) has long been applied in discrete manufacturing operations as a predictive diagnostic technology. Statistical Process Monitoring (SPM), the continuous process version of SPC, has been applied less often as highlighted by Emerson’s Tom Wallace and John Miller in an Intech magazine article, Statistical process monitoring turns process noise into valuable information. […]
