AMMETERS ЭА0302/1У

an improved analogue of Э365

 

device-ea0302u

 

Ammeters ЭА0302/1У of the electromagnetic system, panel, is designed for measuring AC sinusoidal frequency from 45 Hz to 65 Hz.

 

 

 

 

  • Design features:
    • the angular disposition of the movable portion;
    • a liquid damper of the mobile system;
    • a large scale length;
    • the beginning of the measuring range of 10% of final value

Note 1. Depending on the order ammeters with a final value of the measuring range of less than 1 A can be manufactured as a milliammeters and ammeters with a final value of the measuring range of more than 1000 A can be manufactured as kiloammeters.
Note 2. Current transformer should be with a nominal power of the secondary winding of 1 A or 5 A.

 

By special order the ammeters with other measuring ranges and special marks, inscriptions and other functional parts of the scale can be manufactured.
