SENSOR PRODUCTS INC.: Sensor Film

December 4, 2008

Sensor Products Inc. announces Pressurex Zero®, a long-awaited addition to its tactile pressure-indicating sensor films. 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. These variations can result in manufacturing flaws and product defects, especially if the adhesive is not used at the right contact pressure range. The spatial resolution of the film is fine enough to expose minute surface defects and other imperfections. Products and machinery that require adhesives and sealants in the range of 7.2-28 PSI (0.5-1.97 kg/cm2) are candidates for Pressurex Zero.

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.
