Page 9: Types Of Protection
For the equipment category II 2 D or 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. 12/2019 - 4007138001 - AD DK32-34 Exi Gb-Db R01 en www.krohne.com... -
