This lightweight all GRP flameproof sounder is
intended for use in potentially explosive gas and
dust atmospheres and has been designed with
high ingress protection to cope with the harsh
environmental conditions found offshore and
onshore in the oil, gas and petrochemical
industries.
The flamepaths, flare and the body, are
manufactured completely from a UV stable glass
reinforced polyester. Stainless steel screws and
sinter are incorporated thus ensuring a corrosion
free product. A tapered flamepath is used to
overcome the problems of assembly of parallel
spigot flamepaths.
