    E42700 ammeter, voltmeter E42700 (E 42700, E-42700, E42700, E 42700, E-42700; Є42700; Є 42700; Є-42700; e42700; e 42700; e-42700)

    E42700 ammeter, voltmeter E42700 - panel meters for measuring current and voltage in alternating current sine wave.
    Accuracy class - 1.5, 2.5 (ammeter), 2.5 (DVM).
    Dimensions - 80 × 80 × 65mm.
    Weight - 0.35 lbs.
    Structural features E42700

    Ammeters E42700 and E42700 voltmeter are made ​​of two kinds:
    - Magneto system with a rectifier;
    - Electromagnetic system.

    E42700 ammeter, voltmeter E42700 magnetoelectric with a rectifier are measuring mechanism with vnutriramochnym magnet, with bearings on the cores or banners and rectifier in the measuring circuit.
    Structurally E42700 devices of this type are performed with a square front panels and round or square buildings. The degree of protection IP50 housing meet or IP54, protection of current-carrying rods - IP00.

    E42700 ammeters, voltmeters E42700 electromagnetic systems measure AC current and voltage directly to the electrical circuits. Apparatus electromagnetic systems are based on the interaction of the magnetic field of the measured current (current flowing through the coil), with one or more cores made ​​of magnetic material.

    On a design E42700 electromagnetic systems have two types of measurement mechanisms:
    - A flat coil and a movable core of magnetic material;
    - A circular coil with two cores within the coil.

    Measuring the mechanisms of these devices have support for the cores of steel glides.
    Specifications E42700

    The range of measurements and how to enable devices such as E42700 served in Table 1.
