Fujifilm PRESCALE is synonymous with pressure indicating film, pressure sensitive paper, tactile pressure indicating sensor film, pressure sensitive film, Fuji pressure film, pressure tape, Fuji paper, or Fuji prescale film.
Two-sheet type PRESCALE for ultra-super low pressure or medium pressure measurements consists of two types of film:
A-film: Base material (PET base) coated with color-forming material (microcapsules)
C-film: Base material (PET base) coated with color-developing material
The matt finish coated sides of each film must face each other. When pressure is applied, the microcapsules are broken and C film will react and generate a red color and its intensity is responding to the pressure level.
Mono-sheet type Prescale film measures medium to super high pressures with one single sheet of film. A color-forming material and color-developing material are coated one above the other on a PET base material.
When pressure applies on microcapsules, the color-developing material absorbs the color-forming material with a chemical reaction developing a red coloration.
The steps of how to use PRESCALE pressure film are illustrated as follows:
N.B. Do not to touch the coated side of A-film of Two-sheet type, the microcapsules can be broken and the color-forming material will attach to your hands.
Prescale is the only film that measure pressure and pressure distribution in the world. Eight models of Prescale cover a wide range of applications from extremely low to super-high pressures with easy operation. It is recommended that measurements be taken in 30 to 60 minutes after the pressure has been applied. The color density gradually increases for several hours after the pressure has been applied and then, gradually decreases.
- Easy visual check of distribution/uniformity for contact pressure
- Lower cost with no special devices or equipment required
- Quick measurement gives an at-a-glance picture
- Contact pressure shown with differing concentrations of colour can be converted into figures
- Easy digitization to convert pressure density into quantifiable values
