For the equipment category II 2 D and EPL Db, connection to an intrinsically safe circuit with protection level "ib" is required. When connecting the variable area flowmeter to an intrinsically safe circuit with protection level "ia", a higher protection level is given. www.krohne.com 02/2015 - 4001481102 - MA H250/M40-Exi--II2GD-AD R02... -
Page 9: Ambient Temperature / Temperature Classes
For device versions with a heating jacket the temperature of the heating medium does not • exceed the maximum permissible product temperature. For certain device version, lower values apply due to differing boundary conditions (e.g. lining materials). Here the user should consult the technical data sheet. 02/2015 - 4001481102 - MA H250/M40-Exi--II2GD-AD R02 www.krohne.com... - Page 10 The permitted ambient temperature range is indicated on the nameplate; depending on the device version it is Tamb = -40...+65°C / -40...+149°F or Tamb = -25...+65°C / -13...+149°F. The minimum product temperature is -40°C / -40°F. www.krohne.com 02/2015 - 4001481102 - MA H250/M40-Exi--II2GD-AD R02...
