Thermometer / Pressure Gauge ATEX


Thread Starter


Hi All,

I'm new on this forum, hope to find answers and of course give to you answers!

My question is about pure mechanical pressure indicators/temperature indicators (with expansion liquid). Is there any need to have them atex certified?

Thank you
Hi, Thank you!!

My question is if it's necessary to have pressure indicator ATEX for Zone 2, same for expansion fluid thermometer. What is the main difference between a standard pressure indicator and an ATEX pressure indicator?

Thank you!
Hello all, I have similar question for instrument install in Zone 2 area. The Zone 2 define inside the pipe and instrument transmitters install outside the pipe which is safe zone. Does these instrument still require Atex? Any standard to move the transmitter away from the pipe to consider safe?
