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. Lens diameter 21mm, instrument range 0-10m; lens diameter 43mm, instrument range 0-30m; lens diameter 76 or 65mm, instrument range 0-120.
4. The antenna form can be selected as' AM, FM, FT, GM, GT 'type, and the lens material/thread can only be selected as' A' type; The antenna form can be selected as' AP, FP, GP 'type, and the lens material/thread can only be selected as' B' type.
When the thread is 3 ', there is no NP type installation method.
6. The antenna forms are 'AP, FP, GP' types, and only the 'X' type can be selected for process sealing.

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.
