Extreme Low®

Extreme Low® is our newest addition to the Fujifilm Prescale® line. Now you can characterize surface pressure down to an unbelievable 7.2 PSI (0.5 kg/cm2)!

Simply place Extreme Low® pressure indicating sensor film between any two surfaces that touch, mate or impact. Apply pressure, remove it and immediately the film reveals the pressure distribution profile that occurred between the two surfaces. Conceptually similar to Litmus paper, the color intensity of Extreme Low® is directly related to the amount of pressure applied to it. The greater the pressure, the more intense the color.

Extreme Low® is extremely thin (4 to 8 mils) which enables it to conform to curved surfaces. It is ideal for invasive intolerant environments and tight spaces not accessible to conventional electronic transducers.

Like Litmus paper, the color that Extreme Low® sensor film turns has significance. It is directly related to PSI (kg/cm2), and can be visually compared to our color correlation chart or scanned and quantified with one of our optional optical imaging systems.

Extreme Low® reveals the pressure distribution and magnitude between contacting or impacting surfaces.

Extreme Low® has a wide array of uses. For example, Extreme Low® can be used in a bolted joint interface, composite layup, heat sealing and lamination or press. Our pressure indicating film acts as a force sensing resistor. It can measure surface pressure distribution whether it is used as an impact force sensor, seat pressure sensor, as a strain gauge or even as nip impression paper.
