A pressure sensitive measurement film available from Bestech Australia enables the distribution of pressure applied to web material tensioned over rollers to be examined and analysed.

This pressure measurement film utilises the principle of microscopic ink filled capsules embedded in the surface of the film. The rupturing of the capsules is dependent on the amount and location of the pressure applied by the roller(s) to the film, and accordingly, to the web material.

As the capsules rupture, they deposit a red trace on the film, the intensity of which indicates the location and distribution of the pressure applied to the web by the rollers. Therefore, the pressure film indicates if and where the roller(s) need to be corrected to improve the quality of the web material.

The PRESCALE pressure measurement film is first cut to match the width of the web, or rollers, and in a sufficient length to obtain the required sample of the web travelling over the rollers. The next step is to relax the web, insert the film between the roller(s) and the web material, re-tension the web and then slowly run the web to traverse the cut length of the film.

The web tension is then relaxed, the PRESCALE pressure measurement film removed, and it may then be visually examined. Any variances in pressures are instantly revealed.

In conjunction with a suitable scanner and Fuji analysis software, the pressurised film can also be digitised allowing further analysis and storage of the results for quality control purposes.

PRESCALE pressure measurement film is available in seven pressure ranges from 0.05MPa to 30MPa and the precision of the measurements is typically ±10%.

Suitable operating temperatures for this pressure distribution film is between 20ºC and 35°C and depending on the pressure rating of the film, the thickness is between 90 to 110µm.

There are many applications for PRESCALE pressure measurement film other than web analysis, such as automotive gasket tests, tyre tread examination, foot ware design, and related studies.

Bestech Australia provides complete application advice and after sales service for PRESCALE pressure measurement film and many other similar measurement systems and technology.
