New sensor film range maps and measures extremely low-contact pressures
Article Type: New products From: Soldering & Surface Mount Technology, Volume 21, Issue 4
Sensor Products Inc. have introduced Pressurex Extreme Low®,the newest addition to its tactile pressure-indicating sensor films. Eagerly awaited by the engineering community, Pressurex Extreme Low®characterizes contact surface pressure down to an extremely low 7.2 psi (0.5 kg/cm2). The range for Pressurex Extreme Low® 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 colour directly proportional to the actual pressure applied. The precise pressure magnitude (psi or kg/cm2) is easily determined by comparing colour variation results to a colour 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 often result in 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, Liquid crystal display, 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 spaces. 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.
