ATEX Sounders Zone 1 & Zone 2 Weatherproof Ex d – Eaton DB1 Hazardous Area Sounder

ATEX Sounders Zone 1 & Zone 2 Weatherproof Ex d – Eaton DB1 Hazardous Area Sounder

ATEX Sounders Zone 1 & Zone 2

Eaton MEDC DB1 are part of range of lightweight, flameproof ATEX sounders that have been designed with a high weatherproof rating to cope with the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries in ATEX & IECEx Zone 1 and Zone 2 hazardous areas

Electronic circuitry allows the DB1P and DB1HP hazardous area sounders to be switched between two selectable tones by either reversing the supply polarity, or connecting a second voltage supply. The higher output DB1H and DB1HP are particularly suitable for noisy environments.

Stainless steel, one of the most durable materials available on the market, is both hard wearing and corrosion resistant, increasing the life of products in harsh environments and therefore reducing maintenance costs.
