PTA -Line Bendtsen

Measures the air permeability and surface roughness according to Bendtsen

  • Features

    • 1, 2, or 3 heads available in one device
    • Standard measuring range: 25-5,000 ml/min (other measuring ranges also available, e.g. 1-5,000 ml/min)
    • Simultaneous measurement with all 3 measuring heads
    • Fully automated measuring cycle, sample is not influenced manually


    Description

    The sturdy and stable instrument possesses an industrial PC and a touchscreen. It is available with up to 3 heads: top roughness, bottom roughness and air permeability. The large display indicates single values and statistics. The measurement is performed quickly and automatically. The menu navigation
    is clear.


    Test description

    Surface roughness:

    The operator places the sample below the measuring head. By pushing the start button, the measuring head lowers onto the sample and gently clamps it. The test starts. As soon as the preset flow rate (e.g. 1.47 ml/min) is stable, the measuring value is displayed. The test time is adjustable from 1-40 seconds. After test performance, the sample is released. The measuring head returns to its initial position, and the device is ready for further measurements.


    Air permeability:

    The operator places the sample below the measuring head. By pushing the start button, the measuring head lowers onto the sample and gently clamps it. Air flows through the sample at a selected pressure (e.g. 1.47 kPa). As soon as the preset flow rate is stable, the measuring value is displayed in ml/min or μm/Pa*sec. The test time is adjustable from 1-40 seconds. Gurley values are calculated according to the standard and are displayed in Gurley seconds by default.
