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,
can you please give me details about this instrument.
i want to buy this online.

thanks

 

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.

 

What is dynamo?

 

What is dynamo?

Electric generator: http://en.wikipedia.org/wiki/Dynamo
It is more European way, for example in Russian we would say Dynamo Machine.

 

I wasn't sure OP had the same definition.

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

These are AC and DC.
