Placed between contacting or mating surfaces, Sensor Products' Pressurex Zero tactile pressure-indicating sensor film characterizes contact surface pressures from 7.20 psi to 28 psi (0.50 kg/cm² to 1.97 kg/cm²). The product measures and maps pressure magnitude and distribution, and variations in contact surface pressure are visible by the impression made on the film. The film comes in 8 different pressure ranges in a thin clear plastic sheet (4 mil or 8 mil), permanently changes color directly proportional to the actual pressure applied, and conforms to curves. The psi is determined by comparing color variation results to a color correlation chart, and the film can be scanned through one of Sensor Product’s optical imaging systems. Applications include heat sinks, circuit board lamination, LCD screens, biomechanics, press rollers, heat seals for packaging, and squeegees.
