New Pressurex Zero Sensor Film Measures And Maps Very Low Contact Pressures

Madison, NJ - Sensor Products Inc. announces Pressurex Zero, the newest addition to its tactile pressure-indicating sensor films. Eagerly awaited by the engineering community, Pressurex Zero 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 Pressurex Zero is 7.2 – 28 PSI (0.5 – 1.97 kg/cm2).

Pressurex comes in the form of a thin clear plastic sheet (4 or 8 mil), physically similar in appearance to paper. It is available in eight different pressure ranges with the highest measuring impact up to 43,200 PSI (1,300 - 3,000 kg/cm2). 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 can also be scanned through one of Sensor Product's optical imaging systems.

Pressurex is used in the design, manufacture, calibration and quality control of many products. Contact surface pressure variations often result in manufacturing flaws and product defects Mechanical design and assembly of products that depend upon the compressive force of clamps, fasteners, connectors and bolted joints to join surfaces – such as heat sinks and semiconductors – are particularly aided by Pressurex. Products that depend on defined or uniform pressure distribution over the entire contact surface area, such as rollers, printed circuit board and other lamination presses, sealing equipment for food and drug packaging and lcds are prime candidates. Many applications within biomechanics as well as squeeges and wafer polishing require low contact pressures that can be uniquely assessed with Pressurex Zero.

Pressurex is very flexible, which enables it to conform to curved spaces. It is ideal for invasive, intolerant environments and tight spaces not accessible to conventional electronic transducers. Hundreds of industrial, electrical and electronic applications have been found and others are yet to be discovered.

Pressurex measures pressures as high as 43,200 PSI (1,300 - 3,000 kg/cm2). To request a free sample of Pressurex,
