Hi everybody!
I'm Giorgio and I'm a new to Control.com-
What I'd like to ask is this: I have an Electric Heater on a Methane Gas Purification Unit. This heater has n° 4 TC "k" installed that are used to measure the temperatures inside. The signal coming from these elements must be converted in a 4-20mA HART signal, that shall be sent to a thyristor panel that controls the heater. We have to install 4 converters Ex-ia but we want to install them in a junction box in Zone 2. The junction box can be Ex-ia certified or the converters must be installed in an Ex-d junction box? Maybe there is another thread like this in the forum but I have searched with no results.
Thanks in advance to everybody will answer to my question. Bye!!!
