For the proper wrench size seechapter "Dimensions".Warning:The housing must not be used to screw the instrument in! Applyingtightening force can damage internal parts of the housing.If there is strong vibration at the mounting location, the instrumentversion with external housing should be used. See chapter "Externalhousing".The permissible process pressure range is stated on the type label.The instrument should only be operated with these pressures if themounting accessory used also fulfils these values. This should be en-sured by suitable flanges, welded sockets, tension rings with Clampconnections, sealings, etc.Higher process temperatures often mean also higher ambienttemperatures. Make sure that the upper temperature limits stated inchapter "Technical data" for the environment of the electronics hous-ing and connection cable are not exceeded.12Fig. 11: Temperature ranges1 Process temperature2 Ambient temperature4.2 Ventilation and pressure compensationVentilation and pressure compensation are carried out withVEGABAR 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 valuecan change for approx. 5 s by up to 15 mbar.For effective ventilation, the filter element must always be free ofbuildup.Screwing inVibrationsProcess pressure range -Mounting accessoryTemperature limitsFilter elements
