Yes really, on every jet engine TIT is Total Inlet Temperature.

Yep.

I ask because I came across an interesting paragraph in the T56-A-15
service manual yesterday. Went like this...

...measures the turbine inlet temperature by means of
thermocouples...Eighteen thermocouple assemblies are mounted in the
turbine inlet casing of each engine...One thermocouple of each
assembly is connected to the turbine inlet temperature indicating
system, and...one...is connected to the electronic datum control
system. The 18 indicating system thermocouples are connected in
parallel [!!] by the indicator turbine thermocouple harness assembly,

I'm surprised you ever doubted the truth on this one!


So, let's revise.

That's going a bit too far... Nobody can revise the Tarver
Chronicles! :-)


bimetallic thermocouples generate millivolt signals,and paralleling them
would not work.Standard practice is to series-connect them,and compare
to
a
reference junction.Do these assemblies include signal processing to
convert
the mV signal to a digital form,which could then be sent on a parallel
bus?

Sorry Jim, but it does work.

Don't hide behind Google John, we all know you are wrong and know nothing
about the subject. If you want to reply using Google hoping that most guys
won't read your **** that's fine but it only makes you look stupider than
you are( If that's possible) post your answers here for everones benefit, at
the very least it is worth a laugh.
