hello guys
i have pressure/current converter SRI983 where its main electronic component is the coil that changes current to pressure or the opposite .and this transmitter is 24V and 4-20ma .
but i'm facing a big issue of damaged coils for a years and now someone suggested a solution to install a fuse in the loop ( 20 ma ) to protect the transmitter from high current >20ma.
that will be convenient if the current is the cause of this problem.
but it can be voltage , and maybe noise , and maybe something else you know dear guys.
I searched the internet and they said maybe a zener barrier will be my perfect solution because it limits voltage , current , energy as they said .
now i came here to get the final solution , what do you propose guys?
if you propose a zener barrier provide me the right one for my circuit by the current and voltage i provided?
is it loop powered or requires external power ?i heard about earth or ground what should i take into consideration ?
THANKS
