Ask a Question

  • What is the function of the PCWI Compact Crest Meter?

    The Crest Meter has the following functions:
     •   To test the output of the PCWI Compact Detector and to verify the voltage on the visual display
     •   To test the continuity of the leads and to verify the voltage on the visual display
     •   To test the PCWI Compact Detector under load with an applied voltage - this test verifies all earth leads and connections, and partially loads the system
     •   To test the PCWI Compact Detector under full load. This test verifies all earth leads and connections, fully loads the system, indicates pull down voltage and displays actual test voltage. This test is as per Australian Standard 3894.1-2002 for setting test voltages

  • What certification does the PCWI Compact Crest Meter carry?

    Certification is an option, however the Crest Meter can be supplied as checked against a NATA certified Crest Meter.

  • What certifications of compliance do PCWI Detectors carry?

    Australian Standard AS3894.1-2002. This standard sets the guidelines for equipment type, voltages for specific coating types and voltages applied. The Detectors also meets the EMC directive 89/336/EEC, amended 92/31/EEC & 93/68/EEC and carry the CE marking.

    However, due to the method of operation, PCWI Detectors will generate broadband RF emissions when a spark is produced at the probe, i.e.: when a defect in the coating is located. These emissions may interfere with the operation of sensitive electronic apparatus in the vicinity.

    In the extreme case of a continuous spark of length 5mm the magnitude of the emissions at a distance of 3m was found to be approximately 60dBµV/m from 30MHz to 1000MHz.

    It is therefore recommended that this equipment is not operated within 30m of known sensitive electronic equipment and that the user does not deliberately generate continuous sparks.

  • Is AS3894.1-2002 accepted and/or would the Australian Standard comply with a relative International (ISO) Standard acceptable in other countries?

    We believe that AS3894.1 is the world leader in Porosity Standards and should satisfy all International criteria, as there is no equivalent International Standard for Porosity Detection.

    How helpful was this ?

  • It is understood that the Australian Standard AS3894.1-2002 permits both DC high-voltage and DC pulse units for testing coatings of a depth thickness less than 500µm (micron)!

    The PCWI Detector has constant test voltage and current.
