During work on and with the device, the required personal protective equipment must always be worn. Appropriate use VEGABAR 82 is a slave sensor for electronic differential pressure measurement. You can find detailed information about the area of application in chapter "Product description".
(see chapter "Technical Data"). In addition, a temperature derating of the process fitting, e. g. with flanges, can limit the permissible process pressure range according to the respective standard. VEGABAR 82 • Slave sensor for electronic differential pressure...

4. Depending on the application, carry out the adjustment e.g. in the menu items "Min. adjustment" and "Max. adjustment". Parameterization example VEGABAR 82 always measures pressure independently of the pro- cess variable selected in the menu item "Application". To output the selected process variable correctly, an allocation of the output signal to 0 % and 100 % must be carried out (adjustment).
