Product Announcement: Pressurex Extreme Low Pressure Indicating Film

New sensor film range maps and measures extremely low contact pressures.

Published: Monday, June 8, 2009 - 13:47

(Sensor Products: Madison, New Jersey) -- Sensor Products Inc. announces Pressurex Extreme Low, the newest addition to its tactile pressure-indicating sensor films. Pressurex Extreme Low characterizes contact surface pressure down to an extremely low 7.2 PSI (0.5 kg/cm2). The range is 7.2 – 28 PSI (0.5 – 1.97 kg/cm2). Pressurex is available in eight distinct pressure ranges. The highest pressure range reveals pressure as high as 18,500 – 43,200 PSI (1,300 – 3,000 kg/cm2).

Pressurex is coated on a Mylar-based sheet (4 or 8 mil), and is similar in appearance to paper. When placed between contacting surfaces, Pressuex film instantaneously and permanently changes color in direct proportion 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 is used in the design, manufacture, calibration, and quality control of many products. The variations in contact surface pressure that Pressurex reveals are often the result of manufacturing flaws and product defects. Some applications and products that may benefit from analysis with Pressurex Extreme Low include heat sinks, fuel cells, press rollers, circuit board lamination, LCD panel displays, heat seals for packaging, biomechanics, squeegees, and other applications that require very low contact pressures to be assessed.

Mechanical design and assembly of products that depend upon the accurate measurement of the compressive force of clamps, fasteners, connectors and bolted joints, so that the desired pressure distribution over the entire contact surface area is obtained, are particularly aided by many ranges of Pressurex.

Pressurex is very flexible, which enables it to conform to curved surfaces. It is ideal for invasive, intolerant environments and tight spaces not accessible to conventional electronic transducers. The film can be hand or laser cut to any size or shape.
