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 …
Grounding of submersible pressure transmitter or level probes prevents corrosion
Enrico Bossart | Know-howIn industrial applications, the corrosion of pressure sensors is a rather negligible phenomenon, since in the majority of applications, oils (in particular hydraulic oils) are used, and contact with the pressure medium is mainly limited to the pressure channel and the …
Cleaning of submersible pressure transmitters or level probes
Enrico Bossart | Know-howIf the specific pressure sensor design of the submersible pressure transmitter or level probe is selected to measure the filling levels, this often means that the probe is used under environmental requirements which would cause failure of common level sensors. …
