DB3声音报警器

DB3声音报警器
DB3声音报警器,轻重量所有玻璃钢，隔爆型声音报警器供潜在爆炸性气体和尘埃的环境中使用，以应付恶劣环境,设计用在石油、天然气和石油化工行业中具备防护高等级用于离岸及岸上工业以及石油环境。

This range of light weight all GRP, flameproof sounders 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.

An optional Exe terminal chamber is available.

An uncertified version is available for use in non-explosive atmospheres.
