Note:

1. Intrinsically safe instruments (Ex ia IIC T2～T6 Ga) are limited to "B, R" electronic components; "A, B, G" housings.

2. Intrinsically safe + flameproof instrument (Ex d ia [ia Ga] ⅡC T2～T6 Gb) is limited to "C, E" electronic components; "D, H" type housing.

3. Lens diameter 50mm, flange diameter minimum DN50, maximum DN100; lens diameter 80mm, flange diameter minimum DN80, maximum DN150.

4. Antenna form DQ and EQ can only use "A" type lens material.

caveat:

1. Intrinsically safe + explosion-proof instrument, the explosion-proof chamber is strictly forbidden to open the cover;

2. The non-metallic parts of the product casing have potential electrostatic charge to prevent the risk of ignition caused by friction and impact; contact with liquid media is strictly prohibited during installation and use; wipe with a damp cloth when cleaning.

3. When the shell contains aluminum ADC12 or plastic PBT, to prevent the risk of ignition caused by impact or friction.

4. During maintenance, the non-metallic parts of the product casing and antenna should avoid the risk of ignition caused by friction or impact.
