    Accuracy, correctness and precision – Long-term stable pressure transmitters are a must

    Data sheets from manufacturers of pressure transmitters often contain many different specifications on the subject of accuracy. In most cases, however, not all information is relevant. This article explains which information is to be taken into account and when. It also explains why long-term stable pressure transmitters are a prerequisite for cost optimization in demanding industrial applications.

  7. Defective pressure transmitters due to pressure peaks?

    Defective pressure transmitters due to pressure peaks?

    A common problem in applications with water, oil, or other liquids are brief pressure peaks, which are so high that they damage the measuring cell of pressure transmitters. If pressure peaks of this kind occur, a pressure transmitter with maximum overpressure resistance, which requires a very long-term stable measuring cell and powerful electronics, must be used.

    Trafag revolutionises the measuring of highly dynamic pressure curves

    Trafag has succeeded in unifying the highly dynamic response behavior of a test bench sensor and the extreme robustness of a mobile hydraulic pressure transmitter by combining thin-film-on-steel measuring cells and an ASIC developed in-house. The Trafag ASIC TX with an innovative parallel mixed-signal structure is the key to a response behaviour at nearly unlimited speed.

  10. Withstanding the challenges of saltwater: Choosing the compatible steel

    Pressure transmitter with corrosion

    The choice of the material of parts and components is almost always a compromise between performance and cost. This article outlines some considerations when choosing a suitable pressure transmitter for applications with seawater, e.g. in ballast water management systems or desalination units.

  11. How to assess the corrosion resistance

    Trafag Salt spray test chamber

    There are two major criteria to assess the corrosion resistance against salt water of a stainless steel based on material specifications: PREN Pitting Resistance Equivalent Number and CPT Critical Pitting Temperature, both depending on the contents of the material. For practical tests, a good and reliable indication is the salt mist test according IEC 60068-2-52:1996.
