1.11 OPTIMASS 8000 / 8010C / 8300C / 9000 / 9010C
The OPTIMASS 8000 / 8010C and OPTIMASS 9000 / 9010C mass flow sensors / mass flow
meters are designed with intrinsically safe protection type. The marking for the OPTIMASS
8000 / 8010C is as follows:
II 1/2 G Ex ib IIC T4...T1 Ga/Gb
II 2 D Ex ib IIIC T280°C Db
The marking for the OPTIMASS 9000 / 9010C is as follows:
II 1/2 G Ex ib IIC T4...T1 Ga/Gb
II 2 D Ex ib IIIC T385°C Db
The input connections to the OPTIMASS 8010 / 9010C for use with associated apparatus have
the following maximum values:
The marking for the compact OPTIMASS 8300C is as follows:
