temperature sensor?

where to get one that has a read out like a voltmeter. i can put on my dash. cheap to. i want it for my alt. cuz if it gets to hot to burn out, ill turn the car off. thanks

If you want high quality but pricey, http://www.redlion.net/Products/DigitalandAnalog/DigitalPanelMeters/Temperature/CUB5TC.html That one can even trigger an output/relay/alarm, but $135.

Otherwise if you want cheap, just use something designed for a pc. Most fan controllers have temp readouts, then only hard part is extending the thermocouple wire and getting a good mount on your alt. You will need to buy special thermocouple wire (http://www.omega.com) regular wire will not work.

i like the computer idea better. what wire do i get...

i have a better idea, it comes with 4 different sensor wires, i only need 1, so just take wire from there //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Good idea. Thermocouples work by using two different special types of wire materials, there is a voltage difference between these wires that change with temperature. So make sure you splice the wire correctly. I wouldn't use solder or a butt connector, probably just twist the wires together and use a wire nut, then electrical tape the crap out of it.

Also those thermocouple ends will be thin and fragile so be careful when trying to mount it on your alt.

damm this is going to be great, going to make a frame for it in my dash. killer

yeah i know all about that, i build computers and never though of using computer stuff for audio besides comp fans //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

they make ones that measure amp temp, single wire connection.

interesting, recently i was thinking about looking for a temp meter for my sub and amp. just to be curious and see how hot they get.

i was also considering and fabbing up a cooling system with cpu fans to help circulate air as that area is enclosed.

the option of fan control and multiple temp sensors at that low of a price seems like no harm in giving it a shot.
