The MEDC DB3 Sounder is a lightweight and flameproof Sounder designed for use in potentially explosive gas and dusty atmospheres. This MEDC Sounder has been designed with high ingress protection to cope with demanding environmental conditions to be found onshore and offshore in oil, gas and petrochemical industries.
The flame path, flare and the body of the MEDC DB3 are manufactured out of UV stable glass reinforced polyester. Stainless steel screws and sinter are incorporated, ensuring a corrosion free product. A tapered flame path is used to overcome problems of assembly of parallel spigot flame paths.
An uncertified version is available for use in non-explosive atmospheres.
