Peristaltic Waveform Smoothing
Florite International has now incorporated smoothing functionality into its microcomputer-based, programmable instrumentation when encountering Peristaltic waveforms.
Biologically speaking, peristalsis is the process of moving solids through the human gastrointestinal tract. The involuntary constriction and relaxation of the muscles, starting at the esophagus, creates wavelike movements that act to push food forward through the digestive system. Manufacturing often requires a similar method to move particulates, solids or viscous liquids through discrete points of a given process.
The rolling action of a peristaltic pump is used in the Food & Beverage industry for juice production, where solid waste (skins or peels) would clog up a conventional pump. The positive displacement of the peristaltic pump continues to apply pressure, pushing the solid component forward. Peristaltic Pumps are also used in industries such as water and wastewater, mining, chemical, printing
Ultimately, it made the most sense to apply a filter to smooth out the erroneous waveforms. Similar to how an audio filter removes the hiss of a recording but leaves the music intact, the peristaltic filter doesn?t alter the measured fluid or gas. By keeping the oscilloscope in a narrow frequency range, we were able to stay within 1-2 seconds of suppression.
