When to use electronic pressure switches and pressure sensors
| Enrico Bossart | Know-howFor 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. …
What is the difference between accuracy and switch point accuracy of electronic pressure switches
| Enrico Bossart | Know-howMany users face difficulties in selecting an electronic pressure switch suitable for their application, due to the differentiation of accuracy and switch point accuracy in many official data sheets. Nevertheless, there is a significant difference between the switch …
What does temperature compensation or compensated temperature range for pressure sensors mean?
| Michèle Beyer | Know-howNo 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 …
Ex-d vs Ex-i … why should I care?
| Ahmad Desuki | Know-howI 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 …
