Continuous Film Calibration option for selective coating applications uniquely senses the entire coating pattern. Rather than move across a sensor seeking the film edges to determine pattern width, it quickly detects the entire film and feedbacks pattern width and any gaps or breaks in the film itself down to the pixel level. Proprietary user interface easily sets desired pattern width. Any variation in width during a routine verification will result in automatic recalibration of the fluid delivery system settings with no required operator intervention. Since the pattern is evaluated in its entirety and does not traverse over a stationary sensor to recalibrate, time and volume of coating required to recover to optimal pattern characteristics are reduced.
