Visualizing Surface Pressure Quickly, Precisely and Cost-Effectively

Accurate pressure distribution measurement is essential in many industrial applications. Uneven surface pressure can lead to production defects, premature wear, leakage problems or reduced product quality.

Pressure measurement films from Kager Industrieprodukte GmbH provide a fast, precise and economical solution for visualizing pressure distribution across contact surfaces.

These highly sensitive pressure indicating films offer a cost-effective alternative to complex electronic pressure measurement systems and are ideal for industrial quality control, process optimization and laboratory applications.

How Pressure Measurement Films Work

Pressure indicating films visualize applied pressure through a color-changing reaction. The intensity of the color directly corresponds to the amount of pressure applied.

Single-Layer Pressure Film

In the single-layer version, color-filled microcapsules and a developer are integrated into one film layer. Under pressure, the capsules burst and create a visible color reaction.

The color intensity allows the applied surface pressure to be evaluated quickly and easily.

Two-Sheet Pressure Film

In the two-sheet version, the first layer contains microcapsules of different sizes. Under pressure, these capsules rupture and release a reactive liquid that interacts with the color-developing layer of the second sheet.

This creates a pressure-dependent red coloration that enables highly precise pressure analysis, especially in lower pressure ranges.

Evaluating the Pressure Measurement

The color intensity is evaluated using a calibrated color scale and pressure-density diagram.

Step 1: Temperature and Humidity Correction

Environmental conditions such as temperature and relative humidity are first considered to determine the correct pressure response curve.

Step 2: Determining Color Density

The developed coloration is compared with a standard color scale to determine the density value.

Step 3: Calculating the Pressure Value

Using the selected curve and density value, the actual pressure in MPa or N/mm² can be determined.

The resulting force can then be calculated by multiplying the pressure by the colored contact area.
