Control systems rely on accurate measurements coming in from the instrumentation in the process that measures pressures, temperatures, levels, flows and more. For wired instrumentation, it’s not only the accuracy of the measurement device itself, but the impact of the wiring path between it and the terminations into the control system that determines the signal’s […]

Author: Kyle Knutson Batch repeatability is critical in pharmaceutical and biotech manufacturing. Variations between batches that cause deviations require extensive analysis, either in real-time or post-process, to identify how to control and minimize this variation in the future. The consequences of unacceptable batch variation can be anything from extensive maintenance hours, to temporary halts in […]

Control systems rely on the signals coming back from measurement devices to perform control operations and provide feedback to operators. Unfortunately the signal from these devices can be impacted by several conditions. These conditions include damage and corrosion, water or condensation in the junction box or terminal compartment, power supply deterioration and grounds or electrical […]

My friends in Chanhassen have been hard at work on the usability front. I connected with Emerson’s Alexander Miller to find out what’s the latest with the Rosemount 3051 pressure transmitter. Alex pointed to two new innovative features — Local Operator Interface (LOI) and Power Advisory Diagnostic. I thought we might dig into the Power […]
