During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The VEGABAR 81 is a pressure transmitter for process pressure and hydrostatic level measurement. You can find detailed information about the area of application in chapter "Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.
DIN EN ISO 14001. Please help us fulfil this obligation by observing the environmental instructions in this manual: • Chapter "Packaging, transport and storage" • Chapter "Disposal" Exception: Versions with measuring ranges from 250 bar. These are subject of the EU Pressure Device Directive. VEGABAR 81 • Foundation Fieldbus...

The ambient pressure is detected in the measuring cell and compen- sated. It thus has no influence on the measured value. Absolute pressure: the measuring cell contains vacuum and is encapsulated. The ambient pressure is not compensated and does hence influence the measured value. Seal concept The measuring system is completely welded and thus sealed against the process.

3 Product description Slave sensors of VEGABAR series 80 enable in conjunction with Slave sensors VEGABAR 81 an electronic differential pressure measurement. VEGADIS 81 The VEGADIS 81 is an external display and adjustment unit for VEGA plics sensors. ® VEGADIS adapter The VEGADIS adapter is an accessory part for sensors with double chamber housings.
To maintain the housing protection, make sure that the housing lid is closed during operation and locked, if necessary. Screwing in Devices with threaded fitting are screwed into the process fitting with a suitable wrench via the hexagon. See chapter "Dimensions" for wrench size. VEGABAR 81 • Foundation Fieldbus...

When quickly opening/closing the housing cover, the measured value can change for approx. 5 s by up to 15 mbar. For an effective ventilation, the filter element must be always free from buildup. In case of horizontal mounting, turn the housing so that the filter element points downward after the instrument is installed. This provides better protection against buildup. Caution: Do not use a high-pressure cleaner. The filter element could be dam- aged, which would allow moisture into the housing. The following paragraphs describe how the filter element is arranged in the different instrument versions. VEGABAR 81 • Foundation Fieldbus...

In the case of instrument housings with self-sealing NPT threads, it is not possible to have the cable entries screwed in at the factory. The free openings for the cable glands are therefore covered with red dust protection caps as transport protection. VEGABAR 81 • Foundation Fieldbus...
6. Insert the wire ends into the terminals according to the wiring plan Note: Solid cores as well as flexible cores with wire end sleeves are insert- ed directly into the terminal openings. In case of flexible cores without end sleeves, press the terminal from above with a small screwdriver, the terminal opening is then free. When the screwdriver is released, the terminal closes again.

Linearisation A linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. a horizontal cylindri- cal or spherical tank - and the indication or output of the volume is required. Corresponding linearization curves are preprogrammed for these vessels. They represent the correlation between the level per- centage and vessel volume. The linearization applies to the measured value indication and the current output. VEGABAR 81 • Foundation Fieldbus...
