Thanks to all the prompt answers. Some were very creative and funny. Here are two that you all might find helpful (really) Apologies to the list that's already seen each of them. John Subj: Thermocouples Date: 2/12/01 1:24:38 PM Eastern Standard Time From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] John, A thermocouple ( commonly referred to as a "TC") is just two wires, each make of a different material, that are electrically joined at a point. The joint can be as simple as twisting the wires together so that they make electrical contact (not a reliable method). The more common joint is to weld the wires together, expose them to torch hot enough to melt both wires so a bead is formed. There is some law of physics that says that at a dis-similar junction a voltage is produced that is proportional to temperature. So, if the junction is stuck into the exhaust stream and heated it produces a voltage proportional to exhaust temp. If the same junction is connected to a washer clamped between the sparkplug and the cylinder head it the resulting voltage is proportional to head temp. If there is chafing of the wires, and a short develops in the engine compartment then the voltage will be proportional to compartment air temp. If the wires breaks no voltage will be sensed.

However, for a really good explanation of EGTs and CHT's go to Jim Weir's website for RST Engineering and go to the magazine article page for the article on Testing CHTs and EGTs. http://www.rst-engr.com/ Jim is a great resource for us. __________________________________________________ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ____________________________________________________________ T O P I C A -- Learn More.
