Leak tester in the overpressure light version PMD02-CFL

 
  • Description

  • As a renowned leak test equipment manufacturer, APT is the perfect contact for leak testing and leakage detection. The German company offers its customers various systems for leak testing with air and other technical Solutions. The PMD02 series of leakage testers has been used more than 1000 times worldwide and has established itself as a leak detection device in industrial testing technology. Especially the high flexibility and the robustness in combination with an uncomplicated usability have contributed to the success of the leak detector.

    Leakage tester for compressed air leakage detection

    The PMD02 is suitable for testing the tightness of hollow bodies, such as motors, pumps or transmissions. The variety of test programs, up to 100 different, not only ensures a high degree of flexibility, but also allows you to tailor the leak test tester individually to your specific test Tasks. Whether small or large test volumes, the various options allow a precise and fast execution of all test tasks for vacuum seams with up to 10 bar overpressure. In addition, it is possible to use three test channels simultaneously, depending on the design stage.

    The following procedures and specifications are available:

    • One to four autonomous test channels (does not apply to the Lite versions) 
    • Overpressure 100 kPa, 600 kPa, 800 kPa, 1000 kPa, 1600 kPa and negative pressure (-> test air conditions)
    • Relative pressure technique, differential pressure technique, mass flow overflow technique (various measuring ranges and resolutions)
      Compression testing technology, Continuity testing technology (-> procedures)
    • Remote controllable via signal interface (standard), SDI telegrams (-> more info) , ProfiNet und ProfiBus/Interbus (Options)
    • LC graphic display and foil front with status lamps, control buttons and key switch for operation
    • 100 test programs can be stored in the device
    • Interfaces: two serial data interfaces RS232 for data communication, optional two USB interfaces (NEW), optional one ProfiNet interface (NEW), optional one ProfiBus interface (NEW)
    • Optional temperature compensation in difficult environmental conditions (-> more info)
    • Comfortable parameterization via SDI telegrams and the software PMD02-DATA
    • Comfortable analysis of test tasks by means of the software for leak test devices (PMD02-ANALYZE)

    Leakage tester for pressure difference and mass flow processes

    Leak testers of the PMD02 series can be used for the differential pressure as well as the mass flow process or a combination of both methods. During the leak test by means of pressure difference measuring methods, the test sample is subjected to pressure or vacuum. If the pressure measured and evaluated in the test specimen changes, leaks are present. This method enables an automated test sequence for the air tightness test. The measurement resolution is - as opposed to the relative pressure method - as a rule independent of the test pressure. The disadvantage, however, is that thermal and elastic changes to the test piece can falsify the measuring result. In the mass flow process, pressure or vacuum is also applied. In order to determine the mass flow, the air entering and exiting through possible leakages is tracked via a thermal mass flowmeter. Although the sensor system is somewhat sensitive, it allows a very fast test due to the delay-free measuring Signal. We will be happy to help you select the right test technology and determine the optimal cost-benefit strategy for your application. See for yourself!

    Suitable accessories for your leak detector

    With us, you also get useful accessories for your test equipment, which can be used to further increase functionality. Including, for example, the LK3P leakage calibrator, a universal flow-through calibrator for setting up and checking, and software packages to record, manage and evaluate the test results on the PC, as well as many other accessory components. Do you have any questions on the PMD02 leakage tester or our flow tester? We support you with specific know-how and comprehensive expertise in leak testing.
