Hi all,
I am trying to design a system for the following areas.
Class 1, Div 1, and Class 2, Div, 2
i am looking for a barcode scanner that will work in the defined areas, but the ratings are somewhat new to me
and I need help.
I have a scanner, intrensically safe, but the ratings are as follows
Ex protection type
II 2G Ex ib IIC T4
-20 ?C < Ta < +50 ?C
II 2D ibD 21 T135 ?C
-20 ?C < Ta < +50 ?C
Would someone please explain them.
Thanks in advance,
James
