Good morning r/PLC. A noob here, wanted to open a discussion regarding atex standard of control panel.
-
The directive said we need to provide ex-complied enclosure and components. Why the ex rated components are used if the enclosure are already rated? Assuming the panel is always closed in normal operation.
-
Is the PLCs always intrinsically safe? Since PLCs doesn’t really have spark-inducing switches but the io modules are. They’re needed to be ex rated.
-
For example I have non ex rated equipment inside a panel. And want to ex rating it by covering it on ex rated junction box. Can I?
Thanks!
Hi all,
I have a scenario involving Atex certifications that I'd like some advice on.
So I work for a company that does mostly systems integration when it comes to electronics but sometimes we get into product development at least in part.
For one client there is a requirement for atex certification on a product that we're developing for/with them. Now there's a bit of an issue when it comes to who pays for the certification, as each side has reasons for the other to pay. Under normal circumstances I would obviously opt for the other side to pay. But it seems like this product that we're developing might be marketable to other customers so it might make sense to take on the Atex costs?
What are your thoughts on this? And if necessary, how would I make a strong case for taking on this cost? I'm not the one gets to make the call
Hi we gotten new lights(Peli 1975Z0) at our workplace and it's now a flood LED, and is quite useless for my work :(
Do any of you guys know of a better throwy option in that size(2x AA or AAA) with ATEX certification?

Hi, can anyone recommend an ATEX Zone 1/21, Cat 2D area to work with Allen Bradley Micro 820 PLC, there doesn't seem to be a lot out there, Ethernet/IP CIP is the preferred communication protocol. Thanks
Edit: 7in screen is preferable.
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
Hi,
I'm currently involved in a project where we want to design an RF Transmitter that must be compliant with ATEX directive. We already know some of the aspects that we need to address, such as, a sample unit has to be certified, the enclosure must have a special plastic due to electrostatic concerns, IP67, and so on. Also, we know that the factory that produces the enclosure and assembles everything (we are going to do a custom injection mold) needs to be certified and needs to have ISO9001. However, after reading the information we could find online, we couldn't clarify if every unit we produce and assemble needs to be individually tested for some ATEX parameters, or if we only need to perform some testes batch by batch, or if the required annual company ATEX inspection is enough. We are preoccupied with this because we want to minimize the production costs as much as possible, and if unitary testes are needed it will increase our price point significantly.
Can anyone shed some light on this topic?
Thank you for your time.
Hi all,
Possibly grasping at straws but wondering if anyone has experience of labelling ATEX items.
We want to apply a thin (50microns) aluminium foil label onto the back of our handheld measuring device.
Our approvals agency are advising that under 60079-0 clause 8.2 we cannot use have aluminium used in the construction of the enclosure.
My argument is that the label is not part of the construction, but there is no definition anyway of what counts as the enclosure "construction"
Anyone any experience with this?
Has anyone attempted to get Atex certification for esp32? if so were there any additional requirements or bumps in the road?
Any kind of thoughts or concerns regarding certification process are welcomed.
