Selection criteria for pressure gauges: type of pressure
Jürgen Reiser | Know-howWithin the selection criteria for pressure gauges, type of pressure takes top priority. The measurement of gauge pressure, in fact, reliably fulfils the purpose with the majority of processes. However, for numerous applications in industry, pressure gauges for absolute …
Bourdon tube pressure gauge – operating principle
Jürgen Reiser | Know-howBourdon tube pressure gauges are the most frequently used mechanical pressure measuring instruments. Their pressure element is often referred to as a Bourdon tube: The French engineer Eugène Bourdon made use of this functional principle in the middle of the 19th …
Template for the creation of a proof of intrinsic safety for ATEX certified pressure sensors
Stefan Heusel | Know-howIn my last article I introduced you to how the “basic” proof of intrinsic safety can be provided for instruments and pressure sensors approved to ATEX in Europe. Each installer or operator must ensure that the employees in the plant are not endangered and …
Selection criteria for digital indicators
Anna Zeitler | Know-howIn many electronic pressure measurement applications there is a need to have the measured value displayed on site - either as an additional option alongside the processing of the signal within the control system or as a sole control instrument. If the transmitter …
