Two egt gauges off one thermocouple?

[Kvic]

Getting a juice/attitude, and was wondering if my existing thermocouple can feed two gauges, ie attitude and analog gauge. Any help would be appreciated.



Thanks

you would be advised to purchase a "dual Thermocouple" . That is one sheath with two independant t/c's within the common sheath.



They work perfect and no calibration error

i have heard of others using one thermocouple for 2 gauges like you want, and it seems to be ok as long as your gauge is a powered type. if it relies on the probe to power the gauge [like the pricols] then it wouldn't work, but with an isspro or autometer that just takes the signal from it and uses an external power source to run the gauge [amp box on isspro, internal on autometer] it should work ok, but if a dual thermocouple gauge exists, that would probably be the better route, but why not try one, then if it doesn't work, get the dual.

hmm, well I have the dipricol gauges and I have been running the thermocouple feed to my TST box to defuel on the higher settings. so far so good. I might just have to look into one of the double thermocouples

Bob, where would one find this product?



Thanks all for your help

EGT gauges read in micro ohms, When you have 1 thermocoupler in two gauges you dont get an exact reading because of a higher draw. I ran 1 into 2 before just to see, and there is a diffrence! I seen alot of diffrence in the mid range cruising RPM's or 5-900 and a slight diffrence in the upper end.

Not all Isspro EGT gauges have the amp box. Mine doesn't have one. The EV series gauges probably all do (like my transmission temp gauge).
