  • Page 18: Ventilation And Pressure Compensation

    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 • Modbus and Levelmaster protocol...
