AJP Automotive Ltd Prescale pressure sensitive film suppliers
Product Specification

Fuji Prescale pressure sensitive film consists of a thin film consisting of micro-encapsulated colour forming material and colour developing material. A red colour impression of varying density is formed according to the amount of pressure and pressure distribution.  Prescale can be used to measure linear and planar contact pressures up to 300 MPa (43,500 psi) in either moving or stationary applications.

Structure:

Two-sheet Prescale Film: is composed of an A-Film, which is coated with a micro-encapsulated colour-forming material, and a C-Film, which is coated with a colour-developing material. The A-Film and C-Film must be positioned with the coated sides facing each other.

Mono-sheet Prescale Film: The colour-developing material is coated on a polyester base, with the micro-encapsulated colour-forming material layered on top.

How to use Prescale film fig_01

Two-sheet Type (Ultra super-low pressure:  LLLW~Medium pressure: MW)
Cut two Prescale films appropriately. (A-film in black poly sack & 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 colour density changes according to pressure level.
Take out the C-film, see and check the pressure distribution. For further precise pressure values use the pressure analyzing system.

Mono-sheet type (Medium pressure: MS~Super high  pressure: 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 colour density changes according to pressure level.
Take out the film, see and check the pressure distribution.
For further precise pressure values use the pressure analyzing system.
