  • Page 19: Ventilation And Pressure Compensation

    Filter elements Ventilation and pressure compensation are carried out with VEGABAR 82 via a filter element. It is air permeable and moisture- blocking. Caution: The filter element causes a time-delayed pressure compensation. When quickly opening/closing the housing cover, the measured value can change for approx. 5 s by up to 15 mbar. For effective ventilation, the filter element must always be free of buildup. VEGABAR 82 • Foundation Fieldbus...

    Instruments with approvals can have different technical specifications depending on the version. For that reason the associated approval documents of these instruments have to be carefully noted. They are part of the delivery or can be downloaded under www.vega.com, "Instrument search (serial number)" as well as in the download area. 11.2 Supplementary information Foundation Fieldbus The following table gives you an overview of the instrument versions and the corresponding device descriptions, the electrical characteristics of the bus system as well as the applied function blocks.

  • Page 78 The function block "PID Control " is a key component for various tasks in the process automation and is used universally. PID blocks can be cascaded if this is necessary or requested due to differ- ent time constants with the primary and secondary process measurement.

  • Page 79 The function block "Integrator" integrates a continuous input signal over the time and sums the results of an impulse input block. It is used as a totalizer up to a reset or as a subtotalizer up to a reference point at which the integrated and accumulated value is compared with the default values. When these default values are reached, digital output signals will be outputted. The integration func- tion is carried out upwardly starting with zero and downwards with a default value. Two flow values are also available so that the net flow volume can be calculated and integrated. This can be used for calculation of volume and mass changes in the vessel or for optimisation of flow controls. VEGABAR 82 • Foundation Fieldbus...
