Temperature sensor

Post by **Japper** » 15 Nov 2005 11:36 am

Can someone help me find a sensor for the outside temperature. It's called a PT100. I fidled around a bit with some tiny sensor, but they only had 2 wires coming out it them, I need three. The small ones don't uses a ground wire.

why do you need 3 wires? i've not seen one needing 3 before.

The standard one is used to measure 'resistance to ground' (like most sensors), with the two wires being ground, and 'to gauge'.

400 series cars with the info centre use the same sender, if that helps?
