Fujifilm Prescale is a sensor film that quickly and accurately maps and measures pressure distribution and magnitude between any two contacting surfaces. Distributed by Sensor Products, the film measures pressures from 7 to 43,500 lb/in2 (0.5 to 3060 kg/cm2). When placed between contacting surfaces, the pressure film instantaneously and permanently changes color directly proportional to the actual pressure applied; no instrumentation is needed. Variations in contact surface pressure can be corrected through repeat testing with the film. Fujifilm Prescale assists engineers in research and design, assembly, failure analysis, and quality control across many different applications within the automotive industry. Pictured is how pressure variations affect a transmission casing. Areas that contain color differentiation or voids indicate areas of lower pressure that may compromise the gasket.
