Sensor Products Inc. is an official distributor of Fuji Prescale(r) in Canada. Fuji Prescale(r) is a Mylar tactile pressure indicating sensor film that instantly reveals surface pressure magnitude and distribution between contacting or impacting surfaces. When placed between the surfaces, it permanently changes colour directly proportional to the amount of pressure applied.
Prescale(r) shows precisely how surfaces engage and deform under stress. Pressure variations, which can result in costly defects, are shown by the pattern of calibrated pressure left on the film which can be compared to a colour calibration chart. While no instrumentation is required, Sensor Products Inc. also provides imaging services and pressure analysis systems that convert the impressions into colour-coded pressure images and graphs.
The film confirms FEA predictions and has widespread applicability in research, design and test; assembly and production; and quality control and maintenance. Virtually any two contacting surfaces can be captured by the film. Prescale(r) is thin and flexible, allowing it to conform to both curved and straight surfaces. It may be hand or laser cut to fit unusual shapes and dimensions. It is ideal for invasive and intolerant environments not accessible to conventional transducers.
The image shows how pressure variations affect a gasket. Areas that are broken or contain colour differentiations fall between the threshold that keeps the gasket's pressure uniform. Additional testing with the sensor film will verify that uniformity has been achieved. Adjusting pressure with Fuji Prescale(r) is easy. The film is placed between two contacting surfaces and pressure is applied. It is then removed and can be immediately reviewed for proper pressure. Following testing, the control can be archived for future comparisons.
Common applications include measuring the interface pressure of gaskets, clamps, bolted joints, heat sealing elements, nipped rolls, lamination presses, composite layups, welding heads, LCD panels, wafer polishing and bonding, and heat sinks.
