Oguz_ehm Posted December 13, 2009 Report Share Posted December 13, 2009 hi ! I've a project from my college that is called analog ammeter design.I couldn't find something about it.Is there anyone know something about this project.I'm waiting for your helps...

Alex Tsekenis Posted December 13, 2009 Report Share Posted December 13, 2009 What are you required to do in this project? Quote Link to comment Share on other sites More sharing options...
Oguz_ehm Posted December 13, 2009 Author Report Share Posted December 13, 2009 I need analog ammeter's circuit diagram and which materials are used in this circuit.I've been looking for that circuit novadays but I couldn't find. Please help me .. Quote Link to comment Share on other sites More sharing options...
Alex Tsekenis Posted December 13, 2009 Report Share Posted December 13, 2009 You need to tell us more about your project. Do you need to build an analogue current meter yourself? Buy one? Quote Link to comment Share on other sites More sharing options...
Oguz_ehm Posted December 13, 2009 Author Report Share Posted December 13, 2009 Yes I'll built an analogue current meter and for that I need a circuit diagram and materials that are used in this circuit. Quote Link to comment Share on other sites More sharing options...
Alex Tsekenis Posted December 13, 2009 Report Share Posted December 13, 2009 Ok. Very surprised they asked you to build an analogue current meter at college.Is it for DC or AC? A simple current meter could have a coil of wire and a needle attached on a magnet.http://isaac.exploratorium.edu/~pauld/summer_institute/summer_day15current/ammeter.htmlhttp://chestofbooks.com/crafts/popular-mechanics/The-Boy-Mechanic-700-Things-for-Boys-to-Do/How-To-Make-An-Ammeter.html Quote Link to comment Share on other sites More sharing options...
Oguz_ehm Posted December 13, 2009 Author Report Share Posted December 13, 2009 thanks for your links.I'll build analog ammeter circuit for DC current. do you have any idea that i could make that circuit with simple electrical components (for example : resistors.. etc) ?

Hero999 Posted December 13, 2009 Report Share Posted December 13, 2009 Look it up on Wikipedia: http://en.wikipedia.org/wiki/AmeterThis is more of a mechanical project than electrical. Care to mention the current range?You might need a shunt resistor in parallel with the coil but that's about it. Quote Link to comment Share on other sites More sharing options...
Alex Tsekenis Posted December 13, 2009 Report Share Posted December 13, 2009 The ammeter does not really require any resistors to work. It can be just a piece of wire.You might need resistors to increase its range.Another thing you can do is buy a ready analogue volt meter and connect it across a resistor of 1 Ohm.Then the display will be in Amperes. See diagram attached and link.http://uk.farnell.com/tyco-electronics-crompton/e242-89v-g-mt-mt/meter-din48-10vdc/dp/1227831Moving coil or moving iron meters can only measure current really.Regards,Alex Quote Link to comment Share on other sites More sharing options...
Hero999 Posted December 13, 2009 Report Share Posted December 13, 2009 It's not cheap though, you could buy a decent DVM for less than that.A 1Ω resistor would also dissipate 100W at the full range of 10A.You're better off using a 50 Quote Link to comment Share on other sites More sharing options...
Alex Tsekenis Posted December 13, 2009 Report Share Posted December 13, 2009 You need to tell us exactly what you are required to do Oguz_ehm. Quote Link to comment Share on other sites More sharing options...
Hero999 Posted December 14, 2009 Report Share Posted December 14, 2009 Here's a cheaper meter.It's probably not very accurate so will need calibrating.http://www.maplin.co.uk/Module.aspx?ModuleNo=5635 Quote Link to comment Share on other sites More sharing options...
paulgyi Posted December 24, 2009 Report Share Posted December 24, 2009 How can i do Ampere Sensor with electronic device ? Please show me circuit diagram. Thank Quote Link to comment Share on other sites More sharing options...
Alex Tsekenis Posted December 24, 2009 Report Share Posted December 24, 2009 Do you need a digital or analogue display paulhyi?What range of currents? Quote Link to comment Share on other sites More sharing options...
