  • DeltaV Blog: How can you Quickly Increase Production Rate and Efficiency? (Part 1)

    Gregory K McMillan
    When we saw an increase in production rate needed during opportunity assessments at Monsanto and Solutia, we would salivate. Impressive results could be obtained in a matter of a few days by a simple change in setpoint, tuning, and/or configuration. These were quick hits and were often done right at the end of the opportunity assessment while motivation and enthusiasm was at its peak. Once we left the plant, other priorities…

  • DeltaV Blog: How Can You Increase the Rate Time in Temperature Loops?

    Gregory K McMillan
    Temperature loops benefit more than most loops from the use of derivative action. The rate time can be 1/2 of the total loop deadtime or larger by the use of a wireless smart transmitter, the enhanced PID for wireless, and a proper installation location and thermowell design. For many temperature loops, the rate time is compensating for thermal lags that add process and measurement deadtime to the temperature response…

  • DeltaV Blog: Control Using Wireless Devices – The Challenge

    Terry Blevins
    There are significant difference in the frequency and manner in which anew measurement value is updated by a wired transmitter vs. a wireless transmitter. Thus, it is natural to question what impact this has whena wireless transmitter is used in closed loop control. Since most wireless transmitters are battery powered, it is desirable to minimize … Continue reading » Read the full text.

  • DeltaV Blog: What is the Best Transmitter Damping or Signal Filter Setting?

    Gregory K McMillan
    A transmitter damping setting or signal filter setting that is too slow can not only degrade performance but also cause trips. Less understood is that a large filter setting can mislead operations into thinking the filter has helped rather than hurt the process. Too fast of a damping setting or filter setting can decrease the signal to noise ratio and inflict disturbances on the respective loop and other loops. read
