Consider, Gord, that making your little friends look less foolish is only making you look foolish. Yes John... Even if you were to make an "average", you would need a "total" first. Yes John... Yes John.. (oops) OK then. |

My father spent the first few years of WWII changing spark plugs. Was that before or after he was in the 101st in Bastogne? He was bored changing spark plugs, so he volenteered for the 101st. He wasn't bored anymore. |

And bimetal TCs are simply millivolt voltage sources." Yes Jim, what you say is true but it's 'allowed' in this (and other) cases because the voltage output, although in the millivolt range, is 'soft'. so the current is extremely low, they merely 'average' themselves. You certainly couldn't parallel two different voltage sources IF they were 'hard' because huge currents would flow. So on a T-56 engine they do indeed parallel many thermocouples. (I forget how many now, but there's a bunch) Half are used for the FCU and half for the Temperature Datum System. -- -Gord. 18 thermocouples, 3 in each can, each thermocouple has 4 wires connected to it, 2 white, 2 green. 2 wires send signals to the TD amp, the other 2 to the TIT gauge in the flight station via a terminal block.
