Sensor Products: Pressure-Measuring Film
Pressure film displays pressure variations.
Madison, NJ — Sensor Products Inc. has introduced Pressurex Zero®, the newest addition to its tactile pressure-indicating sensor films. The new pressure film characterizes contact surface pressure down to an extremely low 7.2 PSI (0.5 kg/cm2). It is an easy-to-use flexible film that is placed between contacting or mating surfaces to instantly and accurately measure and map pressure magnitude and distribution.

Variations in contact surface pressure are immediately visible by the impression made on the film. The range for the film is 7.2 to 28 PSI (0.5 to 1.97 kg/cm2). The film comes in the form of a thin plastic sheet (4 or 8 microns thick), physically similar in thickness to paper, and is available in eight different pressure ranges. When placed between contacting surfaces, it instantaneously and permanently changes color directly proportional to the actual pressure applied.

The precise pressure magnitude (PSI or kg/cm2) is easily determined by comparing color variation results to a color correlation chart (conceptually similar to interpreting Litmus paper.) In addition, it can be scanned through one of the company's optical imaging systems.

The pressure-measuring film is used in the design, manufacture, calibration and quality control of many products. Variations in contact surface pressure often result in manufacturing flaws and product defects Some applications and products that would benefit include biomechanics, press rollers, circuit board lamination, LCD screens, heat sinks, heat seals for packaging, squeegees, and any other applications that require extremely low contact pressures to be assessed.

The product is very flexible, which enables it to conform to curved spaces. It is suitable for invasive, intolerant environments and tight spaces not accessible to conventional electronic transducers. The film measures pressures as high as 43,200 PSI (1,300 to 3,000 kg/cm2).
