Structure

There are two types of Prescale. Mono-sheet type is composed of a polyester base on which the color-developing material is coated, with the micro-encapsulated color-forming material layered on top. Two-sheet type is composed of two polyester bases. One is coated with a layer of micro-encapsulated color forming material and the other with a layer of the color-developing material. Use two films facing the coated sides each other.

Two types of Prescale(Extreme Low:4LW∼Medium:MW)

How it works

When pressure is applied, the microcapsules are broken and the color-forming material reacts with the color-developing material. Red patches appear on the film.

How to use

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.

Notes
  • * Extra care should be taken in handling the extreme low pressure films. Do not touch, rub or bend the color-forming sheet surface.

Two-sheet type （Extreme Low：4LW∼Medium：MW）

Cut two Prescale films appropriately. (A-film in black poly sack and C-film in blue poly sack) Face the rough surfaces of each film and insert the films where you want to measure pressure. Apply pressure. Red patches appear on the film and the color density changes according to pressure level. Take out the C-film, see and check the pressure distribution. For further precise pressure values, please use the pressure analyzing system.

Mono-sheet type （Medium:MS∼Super High：HHS）

Cut Prescale film in black poly sack appropriately.
Insert the film where you want to measure pressure.
Apply pressure. Red patches appear on the film and the color density changes according to pressure level.
Take out the film, see and check the pressure distribution.
For further precise pressure values, please use the pressure analyzing system.
