    Multiple Atex Certification

    Sorry for the late response, been away for a few days. Cheers Scotty, I was getting there slowly but that explanation was great. St James park, I haven't been there for years. Looking forward to the new season. Lee.

    Multiple Atex Certification

    Wouldn't an Ex ia have limitations on it, circuit wise, that an Ex d would not? i.e. my output from my DCS is not current limited or via a barrier. Lee UTB

    Multiple Atex Certification

    Hello, I've seen this before but not taken much notice of it, but I got a quote through from Emerson for a 3051T pressure transmitter and it has multiple Atex codes. Can be used on Ex d, Ex ia and Ex n. How can this be? Am I being stupid (probably)? Thanks Lee
