Gasification reactors, due to their harsh process conditions, place high demands on the instruments used there. Many manufacturers have reacted to this and adapted their products correspondingly. But what are the optimisation possibilities for thermocouples for use …
Thermowell
Large-scale temperature solution: 37-metre thermowell
Stefan Schneider | WIKA insightAt WIKA USA we are used to dealing with unusually sized temperature solutions. However, this request from a customer was abnormal, even for US standards - during a plant shutdown at the Freeport (Texas) site, it was urgently necessary to replace two flanged thermowells …
Strap-on thermometer or screw-in thermometer? Temperature measurement of pipelines
Roland Sachs | Know-howTemperature is by far the most common measurand in the industry. However, there are no general solutions for temperature measurement. Even when designing measuring points on pipelines, many different factors for selecting thermometers must be taken into account. The …
Heat dissipation
Joachim Brückner | Know-how"At best, a thermometer only ever measures its own temperature". The aim is therefore to equalise the temperature of the sensor element to that of the medium to be measured. Only then will the thermometer display the actual medium temperature. The heat …
Positive material identification test (PMI)
Kai Grabenauer | Know-howThe positive material identification test - PMI test - serves as a proof of the alloying constituents present in the material, confirming the melting analysis of the material contained in the 3.1 certificate. There are two different test procedures common for …
