More DIY EGOR

[Bruce Plecan]

Here's is some more info..
If you go experimenting on you own, be sure not to let the heater warm too
quickly it can crack the inner workings of  the sensor

And again please post here rather then email me.

 > For the heater I have the resistance's  over a range of temps . All this
equipment has up to date >calibrations The oven used is a lab quality Blue M
oven. It has accuracy of +- 2 C  so please   >remember some error in reading
is the fluctuations in temperature in chamber over time and >remember +-2C
this would be worse case. I took this data to verify that my soft start

resistance at any temperature . This means you can use it >as a EGT sensor
as well. I can graph this data as well and give you the equation.  I don't
think this
