Sensor Products Inc. introduces Pressurex®, a contact surface pressure indicating sensor film used in assessing pressure magnitude and distribution between any two contacting or mating surfaces.  In wood production processes, Pressurex® is used to measure pressure distribution of lamination presses as well at the nip of roller coating machines. Pressurex® aids in calibrating nip width contact, and helps to ensure proper alignment of heat seal machinery.  The film is so sensitive that it will reveal voids, pits, microcracks, warping and surface aberrations.

Pressurex® film indicates pressure from 2 - 43,000 PSI (0.14 - 3,000 kg/cm2 ) and is available in seven different pressure ranges. The thin Mylar sensor film changes color permanently and instantly when placed between contacting or mating surfaces. The intensity of the color change is proportional to the amount of pressure applied, allowing the user to quantify the stress characteristics across the surface. 

Pressurex® is a valuable aid for any wood processing situation where materials or solid surfaces come in contact with each other and the distribution and/or magnitude of contact pressure needs to be determined.
