I'm not sure the gland is brass, it's hard to tell in the attached picture. Also, I can't live with the condensation, that is the problem. There is so much condensation inside the device that it is making the Microswitches fail. See the attached pictures...
Sorry, not sure that last attachment was explosion proof.

Please see the attachment. Do you think this would help allieviate the condensaton problem?
Even if they still use cable instead of conduit?

I'm not sure if they have conduit or not. I'm trying to find out. This installation is in Singapore. In some areas over there they just run cables to the device and the cable connects to the device through an explosion proof cable gland.
So I was wondering if a vent in the cable would work...
I'm not sure a heater is an option. This product is an explosion proof pressure switch that is monitoring a fire sprinkler system. It is installed outdoors. I'm not sure what type of power would be available for a heater. Space inside the pressure switch is very limited.
I am aware of explosion...
I have an explosion proof electrical product that is getting a lot of mositure in it that I believe is condensation and I'm trying to prevent or reduce the condensation.
The product is installed outdoors in a very warm to hot rainy and humid environment. It is a NEMA 4 & 9 / IP66 rated...
