1.5 OPTIMASS 2000 / 2010C / 2300C
The OPTIMASS 2000 / 2010C mass flow sensors / mass flow meters are designed with
intrinsically safe protection type. The marking for the OPTIMASS 2000 / 2010C is as follows:
II 1/2 G Ex ib IIC T6...T1 Ga/Gb
II 2 D Ex ib IIIC T150°C Db
The input connections to the OPTIMASS 2010C for use with associated apparatus have the
following maximum values:
The marking for the compact OPTIMASS 2300C is as follows:
For non-Ex i signal outputs
Ex d connection compartment Ex e connection compartment
