Post Body

I'm developing an on-line spectrophotometer to determine the composition of natural gas.

The idea is to put all the elements of the system (valves, spectrophotometer, lamp, fiber optics, wiring...) inside an Ex d enclosure to ensure that the whole apparatus can work in an explosive area.

Now the doubt: the system needs a small air pump to purge the measuring chamber after every sample is measured.

Can a normal (non-ATEX) pump be put in the Ex d enclosure?
How can i feed air into the pump safely?

P.S. First post here, if i'm breaking rules let me know
