<VV> [fastvair] adapter between sending unit and gauge

[mark at noakes.com]

Did you check with the vendor on the linear only aspect? The manual 
talks about multiple calibration points that would address at least some 
nonlinearity but agreed thermistors are more than just a little 
nonlinear. I think they mean multiple linear segments with multiple 
calibration points...aka piecewise linear.

I never thought about it much but something like this could also be 
readily built for nonlinear thermistor signal conversion using an 
Arduino compatible board and analog interface electronics. You could put 
in whatever curve you needed then. The femtodiuno is the size of a 
postage stamp. I used one to convert a slightly nonlinear potentiometer 
analog signal into a digital readout in degrees for a project at work.
