Meas. Pressure Dist. Between Mating Surfaces

Sensor Products”Pressurex is a tactile pressure-indicating sensor film  that isdesigned to quickly and accurately measure surface pressuredistribution and magnitude between any mating or contacting surfaces.In gasket and o-ring seal assemblies, it profiles interfacial contact,showing precisely how surfaces engage and deform under stress to createsealing flaws and inconsistencies. In hydraulics and pneumatics, itimproves fluid power by diagnosing current and potential leakage areasin fittings, couplers, and connectors. Pressurex comes in the form of athin flexible plastic sheet, physically similar in appearance to paper.It detects surface pressure from 2 PSI up to 43,200 PSI (0.14 to3,000kg/cm2 ).  When subjected to pressure, it instantaneously andpermanently changes color. This color change is directly proportionalto the actual pressure applied. Precise pressure magnitude isdetermined by comparing the resultant color intensity to a colorcorrelation chart (conceptually similar to interpreting Litmus paper).
