Note:
1. Intrinsic safety instruments (Ex ia Ⅱ C T2 ～ T6 Ga) use "B, R" electronic components; Type A, B, G shell.
Intrinsically safe and explosion-proof instruments (Ex d ia Ⅱ C T2~T6 Gb) use "C, E" electronic components; D, H "- shaped casing.
2. intrinsically safe and explosion-proof instruments (Ex d ia Ⅱ C T2~T6 Gb) display/programming with "A, B, X" types.
3. The antenna form can be selected as' RW 'or' LG 'type, and the lens material cannot be selected as' D' type.
4. The lens material should be selected as' C 'type, and the antenna form should not be selected as' MW' or 'HG' type.
5. The flange thickness is 10mm, and the installation method 'GD' is only applicable to the antenna form 'HG'.
6. The instrument can be equipped with a blowdown and the interface thread is G1/8. The pressure and flow rate of the blowing air source are shown in the following table:

Warning:
1. For intrinsically safe and explosion-proof instruments, it is strictly prohibited to open the explosion-proof chamber when it is live;
2. Potential electrostatic charges on non-metallic components of the product casing to prevent ignition hazards caused by friction and impact;
It is strictly prohibited to come into contact with liquid media during installation and use; Please wipe with a damp cloth when cleaning.
When the shell contains aluminum ADC12 or plastic PBT, prevent ignition hazards caused by impact or friction.
During maintenance, non-metallic components of the product casing and antenna should avoid friction or impact that could cause ignition hazards.
