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.
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® 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.

Color Intensity Reveals Precise Pressure Magnitude
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.
Pressurex® reveals surface pressure applied to a PCB during the lamination stage
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.
Refer to our applications menu for more detail on any of these uses of Pressurex® for pressure measurement.
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.
