Hi,
Apologies if I'm posting in the wrong place but I'm new to the forum
We're developing a condition monitoring sensor for actuated valves and have run into a technical question that I'm struggling to answer. Does anyone have any insight into how common it would be to have an actuated valve that uses Ex d/Ex m solenoid valves, but where the switch box or position transmitter is Ex ia/Ex ib (Zone 1)?
Do sites tend to adopt a single protection concept for both the solenoids and the position sensing or is it common that protection concepts could be mixed?
Thanks,
Richard...
