Prescale pressure measuring foil

Unique measuring foil for determining the distribution and strength of the pressure.

Single layer type - medium pressure, high pressure, super high pressure (3 types)

In the single-layer film, color-filled microcapsules and a developer are located on a film layer. Under a defined pressure load, the color capsules burst open and discolor the pressure measurement film in proportion to the load.

Two-layer type - extremely low pressure, ultra low pressure, super low pressure, low pressure, medium pressure (5 types)

In the two-layer design, the first film layer carries a layer of microcapsules of different sizes, which also burst open under a corresponding surface pressure and release a liquid that reacts with the highly sensitive color-developing layer of the second layer and causes a pressure-dependent red coloration.

The evaluation is carried out by visual assessment or using the FPD-8010E software in conjunction with a compatible scanner.

How the Prescale pressure measurement foils work
To determine the pressure, its distribution and balance, the Prescale pressure measuring film is placed between two contact surfaces. Layers of microcapsules are attached to the polyester-based measuring film, which break open with a developer when force is applied to the film, leaving a reddish impression image. The imprint image provides information about the distribution and strength of the pressure on the contact surface, as the highest pressure corresponds to the densest red coloration.

The product portfolio consists of eight differently sensitive Prescale pressure measuring foils, which are divided into two types (single and double-layer) based on the technology used. A pressure range from 0.2Nmm-2 up to 300Nmm-2 is covered. The resolution for all film types is 0.125 mm.
