Integration of a pressure sensor element – error compensation of signal for zero point and span
Christian Wirl | Know-howThe installation of a sensor element or a corresponding assembly has the advantage that very compact dimensions are possible. However, some points need to be taken into account, which are an additional effort for the customer compared to using a fully adjusted sensor …
Overload safety of Bourdon tube pressure gauges
Marc Syguda | Know-howThe question occasionally arises, in connection with Bourdon tube pressure gauges, about the overload safety of the instruments. This article deals with exceeding the measuring range by up to 30 %. What happens with the pressure gauge? Does it still indicate precisely …
Traceability
Matthias Bundschuh | Know-howMeasuring instruments for pressure and temperature are used in almost all areas of industrial manufacturing. As a result of continuous mechanical, chemical and thermal loading, these instruments age and can therefore not guarantee the correctness of the measured values …
About the “jungle” of documentation in the calibration world
Christian Elbert | Know-howDue to a modification in the Measures and Verification Ordinance and the metrological traceability policy of the German Accreditation Body DakkS, evolved structures have been considerably muddled up. At first glance, it looks inscrutable and impenetrable. But on closer …
