Electric measuring devices (A-meters and V-meters) of E47 series

Description


These devices are applied in low-voltage complete devices are used in distribution electric circuits of residential, commercial and industrial objects.

E47 A-meters are analog electromagnetic devices designed for measuring current in AC networks.

E47 V-meters are analog electromagnetic devices designed for measuring voltage in AC networks.

Electric measuring devices of E47 series correspond to the requirements of IEC 61010-1, IEC 61326.

E47 electric measuring devices are introduced into the State register of measuring equipment under No. 39231-08. Establishment certificate of measuring equipment CN.C.34.010A No. 33523.

Operating Principle

A-meters and V-meters are devices with an electromagnetic system. They consist of a round coil with movable and rigid cores inside. When current flows through the coil windings, it creates an electromagnetic field magnetizing both cores making the similar core poles repel and axis with a needle spin. For protection from the negative influence of external magnetic fields, the coil and both cores are covered with a metal shield.
