OVERVIEW

boxes & rolls of film

Prescale film can precisely measure pressure, pressure distribution, and pressure balance. Red patches will appear on the film when pressure is applied and the color density changes according to the various pressure levels.

There are seven types of Fujifilm Prescale available to fulfill your varying pressure ranges. (7.25 PSI - 43,500 PSI) (0.05 - 300 MPa)

LINE UP

Seven types of Prescale

Supplied according to pressure level. Select appropriate Prescale.


Pressure Ranges

Notes: W in the product codes indicates two-sheet type and S indicates mono-sheet type.


TECHNOLOGY

Two-sheet type

Extreme low pressure, ultra super low pressure, super low pressure, low pressure (4 types)

Composed of two kinds of films: A-film and C-film

  • A-film: Base material (PET base) coated with a color-forming material (microcapsules)
  • C-film: Base material (PET base) coated with a color-developing material

The coated sides of each film (color-forming and color-developing) must face each other. These are the sides with the matte finish. When pressure is applied, the microcapsules are broken and the color-forming material transfers to the color-developing material and reacts, thereby generating a red color.

Two-Sheet Type

Mono-sheet type

Medium pressure, high pressure, super high pressure (3 types)

Measurement is possible with a single sheet of film.

  • A color-developing material and color-forming material (microcapsules) are coated, one above the other, on a single base material (PET base).

When pressure is applied, the microcapsules are broken and the color-developing material absorbs the color-forming material and reacts, thereby generating a red color.

One-Sheet Type


HOW TO USE

Directions for Using Fujifilm Prescale

Prescale is the only material in the world able to measure pressure!
Microcapsules are broken and react with a color developing agent when pressure is applied.

Step 1

Cut Fujifilm Prescale to desired dimension.

Step 1

Step 2

Insert Fujifilm Prescale in desired location and apply pressure.

Step 2

Step 3

Remove pressure and film. Now, you can see and check its pressure/distribution.

Step 3
