Clutch/Brake
Tactile Pressure Indicating Sensor Film
Pressurex® is a thin flexible mylar film that reveals pressure distribution and magnitude between any two contacting or impacting surfaces. Pressurex indicates precisely how brake pads, calipers and discs deform and engage under stress and is useful as a confirmation of FE analysis. Pressurex's resolution is fine enough to expose minute surface defects and fatigue marks.
Upon the application of force the microcapsules rupture, producing an instantaneous and permanent color change. Like Litmus paper, the color intensity of Pressurex is quantifiable; the color intensity reveals precisely what pressure level (PSI or kg/cm²) was applied at any discrete point on the surface of the film.
