For details of the signal output values, compare the table in section 4 with the CG32…….XYZ
number listed on the data label.
The output connections to the mass flow sensor have the following values:
1.2 MFC 300F & MFC 300F T6
The MFC 300F & MFC 300F T6 have intrinsically safe connections to the mass flow sensor with either
increased safety or intrinsically safe signal outputs. The signal output connection compartment can be
configured with protection type Ex d or Ex e. The marking is as follows:
