Pressurex is available in eight different pressure ranges, with maximum contact pressure measurement extending to 43,200 PSI (1,300-3,000 kg/cm2). It comes in the form of a thin clear plastic sheet (4 or 8 mil), physically similar in appearance to paper. 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).
Pressurex Zero is suitable for the design, manufacture, calibration and quality control of many products that use adhesives and sealants, including sealing equipment for food and drug packaging, LCD panel displays, circuit board and other lamination processes, and the mounting and securing of components at low pressure ranges, such as the squeeze pressure distribution of solder cream on printed circuit boards. Pressurex conforms to curved spaces and is ideal for invasive, intolerant environments, and tight spaces not accessible to conventional electronic transducers.
