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

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.
