Level, pressure, temperature, and flow are all controlled in a similar fashion. Cascade control systems are also more complex than single-measurement controllers, requiring twice as much tuning. Low Temperature Experiment. Sense™ is a series of four individual point-of-use digital mixing valves designed for installation at the point of use to allow user control of water temperature and flow. Variable Temperature NMR using TopSpin 3. The three temps used are room temp, refrigerator, and ice bath. Variable Speed DC Fan Control using the MC9RS08KA2, Rev. Fuzzy Logic Controller (FLC) is best way in.
