Pressure-Indicating Sensor Film Accurately Evaluates Flaws and Inconsistencies in Seals


Pressurex®, a tactile pressure indicating sensor film from Sensor Products Inc., quickly and accurately measures surface pressure distribution and magnitude between any mating or contacting surfaces.

Pressure-Indicating Sensor Film Accurately Evaluates Flaws and Inconsistencies in Seals

Pressure profile across a bolted interface.

In gasket and O-ring seal assemblies, it profiles interfacial contact, showing precisely how surfaces engage and deform under stress to create sealing flaws and inconsistencies. In hydraulics and pneumatics, it improves fluid power by diagnosing current and potential leakage areas in fittings, couplers and connectors.

Pressurex® comes in the form of thin flexible plastic sheet, physically similar in appearance to paper. It detects surface pressure from 2 up to 43,200 PSI (0.14 to 3,000kg/cm2 ). When subjected to pressure, it instantaneously and permanently changes color. This color change is directly proportional to the actual pressure applied. Precise pressure magnitude is easily determined by comparing the resultant color intensity to a color correlation chart (conceptually similar to interpreting Litmus paper).

Pressurex® is used in design and manufacturing as well as in machine and component inspection. It has proven successful in assessing surface contact irregularities in clamps, bolted joints, lamination presses, welding heads, and clutch and brake assemblies, among others.
