Pressurex® is a unique, affordable and easy to use tool that reveals the distribution and magnitude of pressure between any two contacting, mating or impacting surfaces. pressure indicating sensor film is extremely thin (4 to 8 mils) which enables it to conform to curved surfaces. It is ideal for invasive intolerant environments and tight spaces not accessible to conventional electronic transducers.
How It Works
Pressurex® is a mylar based film that contains a layer of tiny microcapsules. The application of force upon the film causes the microcapsules to rupture, producing an instantaneous and permanent high resolution "topographical" image of pressure variation across the contact area.
Simply place Pressurex® between any two surfaces that touch, mate or impact. Apply pressure, remove it and immediately the film reveals the pressure distribution profile that occurred between the two surfaces. Like Litmus paper, the color intensity of the film is directly related to the amount of pressure applied to it. The greater the pressure, the more intense the color.
Pressurex® has a wide array of uses. For example, Pressurex® can be used in a bolted joint interface, composite layup, heat sealing and lamination or press. Our pressure indicating film acts as a force sensing resistor. It can measure surface pressure distribution whether it is used as an impact force sensor, seat pressure sensor, as a strain gauge or even as nip impression paper.

NOTE: You may also have read about pressure sensitive paper, tactile pressure indicating sensor film, pressure sensitive film, Fuji Paper or Fuji Prescale. These terms are synonymous with our Pressurex® pressure indicating film.Pressurex-micro®
The Pressurex-micro® Imaging System is comprised of a sensing mat, scanner, and Windows-based software. By using the Pressurex-micro® mat in conjunction with the scanner and software, the system produces a high resolution full-color representation of pressure distribution.
Simply place the Pressurex-micro® mat in between any two contacting or impacting surfaces. Remove it and immediately see a grayscale pressure distribution profile. The color intensity of the resulting image reveals the relative amount of pressure applied to it. The greater the pressure, the darker the color. The Pressurex-micro® Imaging System's user-friendly software renders information into a clear, easily interpreted image in seconds, with virtually no training required.

Pressurex Zero®
Pressurex Zero® is our newest addition to the Pressurex® line. Now you can characterize surface pressure down to an unbelievable 7.2 PSI (0.5 kg/cm2)!
Simply place Pressurex® pressure indicating sensor film between any two surfaces that touch, mate or impact. Apply pressure, remove it and immediately the film reveals the pressure distribution profile that occurred between the two surfaces. Conceptually similar to Litmus paper, the color intensity of Pressurex® is directly related to the amount of pressure applied to it. The greater the pressure, the more intense the color.
Pressurex® is extremely thin (4 to 8 mils) which enables it to conform to curved surfaces. It is ideal for invasive intolerant environments and tight spaces not accessible to conventional electronic transducers.
Like Litmus paper, the color that Pressurex® sensor film turns has significance. It is directly related to PSI (kg/cm2), and can be visually compared to our color correlation chart or scanned and quantified with one of our optional optical imaging systems.
Pressurex® reveals the pressure distribution and magnitude between contacting or impacting surfaces.
Common Applications include
• Heat Sink• Lamination Presses
• Roller Pressure
• Squeegee Pressures
• Wafer Polishing
