EEx barrier Siemens

Обзор



The EEx barrier is included in the scope of delivery of the CD 6 sensors in EEx ia version. It is meant for wall mounting close to the location of the LDS 6 central unit within an EEx-safe environment.

The EEx barrier defines the interface between the analyzer central unit and the intrinsically-safe sensor heads and ensures under all circumstances that the total electrical energy transferred via the hybrid cable to the sensors is always less that than needed to ignite combustible gas mixtures.
