IMPORTANT
– When used in hostile environments (e.g. oil platforms
where the instrument is exposed to salt spray or diesel) it is
recommended that the FGD10B is always fitted with its protective
weather guard. The weather guard is attached with tamperproof screws
to ensure that it is not inadvertently removed.
The unit comprises an instrument housing having two cable gland entries,
one of which is normally fitted with a certified blank, and containing the
connection terminals and electronics.
The housing containing the gas sensor has an M27 thread and is screwed
into the bottom of the unit. The sensor housing itself is a certified component
and must not be removed in service.
The main electrical features of the unit are:-
•
Power supply
– 8 to 24 volts dc (non-intrinsically safe)
•
Loop powered 4 to 20mA dc
