Transcription

1 Bourdon tube Bourdon tube pressure gauges for chemcal applcatons wth glycerne fllng EN 837- For chemcal and process engneerng applcatons Measurng system fully welded to housng Extremely robust desgn Can be used n case of heavy vbratons and hgh, dynamc pressure loads Tghtness-tested wth helum DNV- and GOSSTANDART-certfed ATEX verson (optonal) Pressure gauges A Page 5 Applcaton For corrosve gaseous and lqud meda whch are not hghly vscous and do not crystallse; sutable for corrosve envronments. For measurements n areas wth hgh vbraton levels and hgh, dynamc pressure loads.! For measurng gas or vapour, these gauges must be used n accordance wth the table "Selecton Crtera as per EN 837-2" (see appendx)!
