    hello friends,

    can anyone help me in finding a device for measuring ampere in dyanamo.
    i must see the reading on a digital display how it is increasing.
    even iam intrested in know the RPM, if rpm is low it must send a signal, if it is high must get a signal.

    Regards
    Afroz

    An ordinary DVM will do, on 10-30 amps range.

    hello sir,

    i want to measure it automatically and send signal wheather it is high are low ampere when dyanamo is running.

    eg:-

    i started a motor it is measuring 10amp its ok if it is less than 10amp it should give a alaram signal to stop motor.


    Thanks

    I assume DVM means digital volt meter. Since we are talking current here, I think the earlier poster was referring to DMM (digital multimeter). Again, since we are talking about measuring current, a current meter might be even better. However, all these devices are manual, a person takes measurement and makes the decision of what to do, turn motor off or keep it on.

    You seem to want some automation. This requires more information. Provide a short description of what the device must accomplish (you keep talking about current and revolutions so we don't know what you REALLY want), provide requirements, provide constraints.

    I wasn't sure OP had the same definition.:confused:

    Dynamo is DC. Description leaned toward something else. Possibly!

    These are AC and DC.
