Pressurex Zero from Sensor Products Inc., Madison, NJ, is a tactile pressure-indicating sensor film with a sensing range of 7.2 to 28 psi. The flexible film is placed between contacting or mating surfaces to measure and map pressure magnitude and distribution. Variations in contact surface pressure are visible by the impression made on the film. Spatial resolution is fine enough to expose minute surface defects and other imperfections. Pressurex is available in 8 different pressure ranges; pressure magnitude can be determined by comparing color variation results to a color correlation chart or scanned through one of the company's optical imaging systems.
