Because we at CSC Scientific provide test equipment for both on and off line moisture testing we have a unique and non-biased perspective on the question of on-line vs off-line. We developed six useful keys that can be used to resolve the dilemma of choosing between on-line and off-line moisture testing.
The promise of testing moisture on-line is like a siren’s song. All you do is plop the device on your production line and voila, continuous moisture reading and perfect process control. If it were only that easy you wouldn’t need these keys. I’m sure you know that the off- line solution has a cost advantage of three to five times and is much simpler to set up. Consequently, to choose on-line, a thorough analysis is needed of the benefits.
These six keys will get you started in the analysis process to ascertain whether the on-line or traditional off-line approach is most suited.
If all three of these conditions are a part of your operation the on-line solution should be considered.
In evaluating an application for moisture measurement, you can use these six keys to narrow the scope of solutions to be investigated. In the selection of either approach, there is a wide span of equipment choices. In my years of experience, I have found that using these keys helps get a focus on the best solutions and helps identify the most appropriate equipment.
We’d like to hear of your experience in dealing with the on-line / off-line decision.
