Fujifilm's Prescaleā„¢

Pressure indicating film is used to measure contact pressures as low as 7.25 psi up to pressures as high as 43,500 psi. When pressure is applied, tiny microbubbles burst within the film to show the various degrees of pressure, through color density, that corresponds to the pressure and pressure distribution.

Features & Benefits of Prescale Film

  • Affordable and easy to use
  • One-time use
  • Static pressure measurement
  • Peak pressure snapshot

How Prescale Film Works

1. Cut Prescale Film to desired dimensions 2. Insert film and apply pressure 3. Remove Prescale and check density1. Cut Prescale Film to desired dimensions 2. Insert film and apply pressure 3. Remove Prescale and check density

Simply place Prescale film between any two surfaces which come into contact. Varying colors of red patches will instantly appear revealing the pressure distribution between the surfaces. The intensity of the red colors of the Prescale film is related to the amount of pressure applied to it; the more intense the color, the greater the pressure.

There are seven different film types available ranging from 0.05 to 300 MPa (7.25 to 43,500 psi):

  • 4LW Extreme Low
  • LLLW Ultra Super Low
  • LLW Super Low
  • LW Low
  • MS Medium
  • HS High
  • HHS Super High

Please see the Specifications tab for details about each type.

For enhanced data analysis of the film, the Prescale Digital Analysis System is also available.

Note: Please contact Tekscan for pricing on shipments over 5 rolls. Prescale Film can be delivered only to the United States and Mexico at this time. For further information please contact us at 617-464-4282 or by email at info@tekscan.com and we will be happy to help you with your order.


 

Film Types: Two-sheet vs. Mono-sheet

Two-sheet Prescale Film (Extreme Low pressure through Low pressure):

Composed of two polyester bases, A-Film and C-Film. A-Film is coated with a micro-encapsulated color-forming material, and a C-Film, which is coated with a color-developing material. The A-Film and C-Film must be positioned with the coated sides facing each other.

Two Sheet Film TypeTwo Sheet Film Type

Mono-sheet Prescale Film (Medium through Super High pressure):

The color-developing material is coated on a polyester base, with the micro-encapsulated color-forming material layered on top.

What Could Dynamic, Real-Time Pressure Data Add To Your Process?

While pressure film can be effective in capturing static peak pressure loads, an I-Scan™ System offers several features and benefits to help you capture more robust, real-time data. Watch this video and see how these pressure test & measurement technologies compare.
