The production of semiconductors places high demands on pressure measurement technology. Pressure transducers there, for example, are deployed in a UHP “ultra high purity”) design. This article explores the question of why such high-quality instruments are necessary and what properties they must have.During semiconductor production, the pressure transducers are exposed to highly aggressive, toxic or … Read more
In connection with the electronic pressure switch PSD-30, I often get asked what is IO-Link and how it is defined. IO-Link is a new communication interface in the area of factory automation/ machine building. Leading providers of automation technology have joined together to form the “IOLink consortium” and specified this new interface. Relentless can be … Read more
Through Vendor Managed Inventory (VMI), the capital tied up in the customer’s warehouse is minimised, the availability of bought-in parts is maximised at the customer (maximising the levels of service) and thus the typical materials planning problems are solved.Typical materials planning problemsWith the supplier, precise information on the actual demand of his customer is not … Read more
Companies in the food industry use electronic pressure transmitters to monitor the pressure in a UHT plant. In order to optimise its process reliability, a manufacturer of dairy products has now upgraded its system to utilise the WIKA DMSU21SA pressure transmitter with integrated diaphragm monitoring. The previously installed measuring assembly leaked due to damage to … Read more
The DIN 3852-E pressure connection thread standard has been invalid since 2012. The standard that has been valid since then for pipe threads (e.g. for G ¼ A) is DIN EN ISO 1179-2: “Connections for general use and fluid power – Ports and stud ends with ISO 228-1 threads with elastomeric or metal-to-metal sealing…”. Now, … Read more
Temperature ? a term that people use daily as a matter of course, without being made aware of the physical correlations. But how is the term temperature defined?Everybody perceives temperature in their environment purely subjectively. If we have been too warm or too cold, this is a feeling, which might be different from individual to … Read more
At the finish of 2018, for a flow measurement application in India, the WIKA Group manufactured a PTC-6 nozzle with a diameter of 18 inches for the very first time ? and in an archive time of just 20 weeks. The entire amount of this nozzle, including upstream/downstream piping, is 13.3 metres.Trusting cooperationThe order was … Read more
Many customer wonder why hydrostatic level sensors fail because of lightning strikes, even if they ordered a level sensor with integrated lightning protection. Understanding how the lightning protection works and how lightning strikes affect hydrostatic level sensors is important in resolving this confusion.When submersible pressure sensors, a special kind of hydrostatic level sensors, were first … Read more
Being faster than a snail is a tremendous challenge for a tunnel boring machine. Students at DHBW Mosbach have mastered this, and have made it through to the final of an international competition with the ?Dirt Torpedo?. WIKA co-sponsored the project by giving measurement technology and a grant.Students at DHBW Mosbach proudly presented their ?Dirt … Read more
Pressure gauges in safety version made from stainless steel are of great importance, especially for critical processes in the process industry. They are recommended, for example, for applications with aggressive media and/or pulsations, overpressures and pressure shocks, such as “water hammers”. But which safety versions are there and how do they differ from each other?The … Read more
