I wonder if anyone has ever tried to connect 1 gauge, CHT that is, to 2 cylinders. I can envision the leads coming from the spark-plugs connected to a toggle switch or some type of selector switch and then on to the gauge. Switch to the right, and I get the temp of the right side, switch to the left and I get the left side temp. Could it work? Did I read somewhere that the length of the wire has something to do with the accuracy?
I know there are gauges out there that will show temps on all 4 cylinders, but I do not want to invest that much. Just looking at the VDO CHT gauge. Any thoughts, Clark |

I agree, the thermocouple wire would be more expensive than an additional gauge. Thermocouples generate a small (millivolt) signal from heat, the gauge amplifies that to a decent signal and gives your reading. Any time you have a "cold joint" in a thermocouple system, you loose some of the millivolt signal. A switch not made for thermocouple would basically render the signal useless.
Its covered here http://www.omega.com/temperature/Z/pdf/z004.pdf Omega is generally considered the leaders in temp/force applications. |
