Fujifilm Prescale Range• Prescale film can precisely measure pressure, pressure distribution, and pressure balance.
• Fujifilm's advanced technology in color film manufacturing enables Fuji to produce extremely thin and stable Prescale films of less than 200μm(100μmx2)
• 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 Prescale available to fulfill your varying pressure range.(0.05∼300 MPa)(7.25 psi∼43,500 psi)
» Strong Points :• Easy visual check of distribution/uniformity for contact pressure.
• Contact pressure shown with differing concentrations of color can even be converted into numbers.
• Lower cost with no special devices or equipment required.
• Quick measurement gives an at-a-glance picture.
» Line Up :Seven types of Prescale are supplied according to pressure level. Select appropriate Prescale.
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.
• Two types of Prescale(Extreme Low:4LW~Low:LW)
» 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.
• Mono-sheet type (Medium:MS~Super High:HHS)
» 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.
» Specifications and Operational Environment :• Accuracy : ±10% or less (measured by densitometer at 23°C,65% RH)
• Recommended service temperature : 20°C~35°C( 68°F~95°F)(*1)
• Recommended service humidity : 35% RH ~ 80% RH(*2)
• Thickness : mono-sheet type(S): 100µm
two-sheet type(W):100µm x2
» Pressure Chart (Low Pressure case)Continuous pressure :• Measurement pressure range:Low pressure (2.5~10 MPa)
• Pressure application condition:Time to reach the pressure 2 min.
• Time of retention at the pressure 2 min.
* Taking the temperature and humidity condition into consideration, select a curve among A, B and C.
