You can insert a 4-cores shield cable (2 Twisted Pairs) on the wiring from control room to the tank area into a 3/4” galvanized steel pipe in order to meet the requirement of electric wiring.
Adopt Explosion-proof Flexible Pipe on the probe cable, screw down the tie-in of the Explosion-proof Flexible Pipe and the seal bolt on the probe.
Add a 6’’to4’’bushing and a copper nipple at the other end of the Explosion-proof Flexible Pipe which should be connected with the Explosion-proof Junction Box. The inner connection bolt of the Explosion-proof Junction Box should be wired reliably and the outer grounding terminal of the Explosion-proof Junction Box should also be grounded reliably. Flanges should be grounded reliably .
