Film measures force between surfaces

Pressurex is a tactile force indicating sensor useful for measuring compression magnitude and distribution between two mating or impacting surfaces. In plastics manufacturing, applications include: machine calibration for pressing and forming equipment (a lamination press for example); assessing roller nips; checking pattern and pressure level in molds; measuring horn interface pressure during ultrasonic welding.

The Pressurex sensor is in the form of a large, thin film. When placed in between impacting surfaces, the film changes color proportionately to the amount of force applied. Precise kn/cm2 (psi) can be determined by comparison between the film and a color calibration chart.

With a maximum thickness of 8 mils, the film can be used in environments that cannot accommodate traditional load cells and other transducers.
