Hi Victor,
I agree, the digital stuff is ok for an accurate measurement at a point in time but for ongoing monitoring I like to see needles moving.
I havn't fully set up my own system as yet (in the final stages though) but I was thinking along the same lines on a voltmeter and an ammeter.
I did have it in mind as to whether i could have two volt meters; one to view the turbine output and a second to monitor the battery voltage but as soon as you connect the turbine with the battery (even if you measure the volts before the blocking diode) the volts stabilise irrespective of the turbine speed and output.
As to the meter ranges, if you want to have this as a fixed set up and don't want to measure open voltages (no batteries or load connected) then a 0 - 20 volt meter would be more than fine. I've got a 0 - 15V unit that I plan to use. As for an ammeter, it depends on your generator. If you're using an Ametek or a treadmill then 0 - 10 amp should be fine. I've got a couple of old car ammeters that have a 0 - 30 amp scales but most of the time I won't see them even flicker as their range is too high and the gauge is too physically small.
Hope this helps
Cheers
Del. |
