Page 8: Principle Of Operation
Enter serial number manually in the VEGA Tools app (available free of charge in the respective stores) Principle of operation Application area VEGABAR 19 is suitable for applications in virtually all industries. It is used for the measurement of the following pressure types. • Gauge pressure Measured products Measured products are gases, vapours and liquids. - Page 9 Relative pressure: the measuring cell is open to the atmosphere. Pressure types The ambient pressure is detected in the measuring cell and compen- sated. It thus has no influence on the measured value. Recessed installation The recessed installation is particularly suitable for applications with gases, vapours and transparent liquids. VEGABAR 19 • Two-wire 4 … 20 mA...

Page 12: Mounting
Use a suitable connection cable (see chapter " Connecting to power supply") • Tighten the cable gland or plug connector • Lead the connection cable downward in front of the cable entry or plug connector VEGABAR 19 • Two-wire 4 … 20 mA... - Page 13 This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through cleaning processes) and on cooled or heated vessels. Ventilation and pressure Ventilation and pressure compensation for VEGABAR 19 are provided compensation by an air-permeable, moisture-blocking filter element. Fig. 6: Position of the filter element Filter element For effective ventilation, the filter element must always be free of buildup.
