  • Pressure measurements yield important information in many different situations. The flying height of aircraft is determined by measuring the air pressure. In this respect it is important that the pressure meters are traceably calibrated in order to determine the correct height, so safety can be guaranteed.

    Pressure is important in many consumer products too. To prevent crisps landing on the consumer’s table as crumbs, the crisp bags are filled with nitrogen gas under a specific pressure. If the pressure is too high, the bags burst. The explosion risk becomes more serious when dealing for example with the filling of gas bottles under pressure.

    VSL supplies various services in the pressure field for the process industry, healthcare, the oil and gas industry, and analytical and chemical laboratories. VSL also provides calibrations to accredited institutions that use pressure balances and other pressure measurement devices.

    In many manufacturing processes, pressure plays an important role in ensuring quality and safety. Certainly now that more processes are automated, it is crucial that the pressure measurements proceed accurately and reliably. VSL calibrates and adjusts pressure measurement equipment with a low measurement uncertainty. Absolute, relative (gauge) and differential pressures are  possible.

    During calibration, corrections are made for various effects that influence the measurement, such as temperature and local gravity. The results of the calibrations conducted are traceable to primary and internationally recognised measurement standards.

    Calibrations for accredited laboratories
    Accredited laboratories can improve and underpin their quality systems by having their measurement instruments calibrated by VSL.

  • To ensure optimum quality of their measurements, laboratories frequently hold in-house quality checks. However, over time deviations in the measurement equipment can occur that cannot be detected by these checks. VSL regularly organises (international) interlaboratory comparisons, through which your laboratory’s measurement results are compared anonymously to those from VSL as primary standards laboratory and those from other participating laboratories.

    VSL regularly organizes various interlaboratory comparisons for pressure testing:

    Need for a different  comparison? 
    Do you require another type of proficiency testing? Then please let us know. We can assess the demand. Possibly there are other laboratories that would like to participate, then we can organise an ILC. It is also possible to organise a bilateral comparison with VSL.

  • Would you like to know more about the measurement of pressure? VSL offers a standard training course and customized training courses that are adapted to your specific knowledge needs.

    VSL training courses are always presented by specialists in their field. Theory and practice are always combined.

    After the course ends, you receive proof of participation.

    Pressure course
    The standard pressure training course is called ‘General Pressure Measurement’. During this course, the following subjects are discussed:

    • Concepts and units: from Pa to kgf·cm-2.
    • Procedures and standards in accordance with ISO/IEC 17025.
    • Pressure balances, manometers, pressure sensors.
    • Measurement principles and uncertainty analysis.
    • Calibration setups and disturbing influences.
    • New developments.

    For a complete overview of the courses planned and in order to register, please click here.

     

  • Various manufacturers of measurement instruments calibrate these in their own calibration facilities. They do this to check that the newly-produced instruments comply with the requirements, to check stability, or for periodic recalibration. Of course, the purchaser of the measurement instrument must have faith in the facility and so the measurement uncertainty is important.

    Test facility performance
    VSL offers CMC Certification. CMC stands for Calibration and Measurement Capabilities. In this, only the performance of the test facility is considered. You receive a certificate containing the calibration facility’s measurement uncertainty and a manual about traceability. With this certificate, you can demonstrate that the measurement uncertainty has been established by an authoritative and independent national metrology institute (NMI).
