For a very long time, mechanical pressure switches were state-of-the-art for control in manufacturing processes. Modern pressure sensors seem to be the answer to the demand for data collection and control, by providing continuous data output about the process pressure. …
No other term is as misleading as "compensated temperature range". Let´s first begin with what is meant: The compensated temperature range is the temperature range in which the temperature error, and accordingly the temperature coefficients, are valid. Not, as one …
I was a freshly graduated mechanical engineer when I started my career in the maintenance department of a petrochemical plant. One of the many jobs that we needed to attend to was checking the status of the pressure transmitters that were installed on our production …
In Europe plants or machines used in hazardous areas must comply with the ATEX directive 94/9/EC. Therefore, the pressure sensors or other measuring instruments approved according to ATEX must be used only in conjunction with ATEX approved isolated barriers if they use …
When using pressure sensors and pressure transmitters, our customers often ask for explanations of frequently used terms and abbreviations in connection with "SIL applications". SIL – which means Safety Integrity Level, and PL, which means Performance Level, are …
