EX proof UT flaw detector !

Hi...

we are looking for an EX proof UT flaw detector. We know there are some EX proof
thickness gages ( for ex. cygnus ) available !

If somebody have an idea, please drop me a line !

I don't believe ther eis a total Ex flaw detector system on the market - system becomes non EX when you connect and disconnect probes unless you install numerous barriers.

If its ahazardous area why can you not work under gas detectors and a hot work permit its done daily around the world.

You could get a probe cable sealed at the probe end then but detector and connector in a sealed and purged box with a see through window.
