    Microammeter EA0632 - a device used to measure the electric current in DC circuits.
    Accuracy class - 1.5, 2.5.
    Measurement range - 0 - 30MKA.
    Overall dimensions - 80 × 80 × 49mm.
    Weight - 0.16 lbs.
    Microammeter EA0632 used at various sites the area of defense and security, and other areas of the state metrological control and supervision.

    Structural features EA0632

    Instruments EA0632 are switching panels magneto system vnutriramochnym magnet.
    Microammeter EA0632 has a uniform scale of the gauge indicator. The moving part is mounted on extensions. The device is made ​​in small plastic cases that protect the measuring element from dirt and damage from dust and splashes.
    Operation Microammeter type EA0632 based on the interaction of the magnetic field of the permanent magnet with the electric current passing through the winding frame.

    Specifications EA0632

    EA0632 instrument for measuring ranges, the voltage drop across the resistance of the external circuit, the method of incorporating served in Table 1.

    Table 1.

    Limits of error, which may allow EA0632 microamp current measurement does not exceed 1.5% or 2.5% of the core readings.

    Microammeter EA0632 under the influence of various factors can prevent these errors in the measurements:
    - When the ambient air temperature deviation from normal to any temperature within the limits established by the working conditions of application - no more than ± 1,2% or ± 2% for every 10 ° of temperature change;
    - If you change the device from its normal position in any direction by ± 5 ° - no more than half the limit of acceptable basic error;
    - Under the influence of an external constant homogeneous magnetic field with induction of 0.4 kA / m in the worst direction of the magnetic field - do not exceed more than ± 1,5%.

    Mean time to failure microammeter EA0632 - 49,000 hours, and the average life of equipment is 12 years.

    Operating conditions EA0632

    Microammeter EA0632 designed for use in the following conditions:
    - The ambient air temperature - from -30 ° C to +50 ° C;
    - Relative humidity of the environment - 95% (at +30 ° C).

    Microammeter EA0632 able to withstand these types of loads:
    - Hitting an acceleration of 30m / s 2, the frequency of 10ud/min - 50ud/min;
    - Vibration acceleration of 5 m / s 2 and 50 Hz.
    The manufacturer guarantees that the device specification requirements under normal use, storage, transportation and installation. Microammeter EA0632 compliant, ensuring the safety of life, health, consumer and environmental protection.
