(SPI: Madison, NJ) -- Sensor Products Inc. (SPI) is an official distributor of Fuji Prescale, 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 color directly proportional to the amount of pressure applied.

Prescale 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 color calibration chart.

The image below shows how pressure variations affect a gasket. Areas that are broken or contain color differentiation fall below 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 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.
