Pressurex Extreme Low pressure-indicating sensor film
Aug 18, 2009
Pressurex Extreme Low pressure-indicating sensor filmPressurex Extreme Low is 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 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 color directly proportional 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 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, lcd panel displays, heat seals for packaging, biomechanics. squeegees, and other applications that require very low contact pressures to be assessed.
