PRESCALE

Prescale allows you to easily measure pressure distribution and range. Created using Fujifilm’s advanced thin film coating technologies, the pressure inspection sensor on the entirety of the film allows you to confirm pressure distribution of the entire surface at a glance. The colour appears red where pressure is applied, and the colour density varies according to the amount of pressure. To cover a wide pressure range (0.006 to 300 MPa), Fujifilm Prescale excellent for the applications below:

Prescale Applications:

1)Nip Pressure    

Industries: Battery, Paper manufacturing, printed circuit board, electrode plate pressing, display, Rubber roller mounting quality, etc.
