NTC test circuit UNLISTED

An attempt to simulate a temperature sensor.

This is a signal converter from temperature (NTC) to voltage, used in an other CL project. It’s a test circuit only so the cap in parallel to the sensor is disconnected, also it would be counterproductively here because of the (for the other circuit) required short simulation time.

The NTC is represented by an ugly “workaround” using a current source, which in fact accepts a voltage (very intuitive !) taken from a label.

The sensor itself is from EPCOS, R/T characteristics “8016”, having 10 k at 25 °C, see: http://www.epcos.com/inf/50/db/ntc_09/MiniSensors_B57861_S861.pdf + You have to add another underscore before and behind the "B57861" in the link to get the page, I can't do it here because of formatting issues, also in the following formula there is italic instead of "*" ...

I found a simple formula to convert from temperature (°C) to resistance: Res[kOhm]=32-0.035temp+28(EXP(-0.06*temp)-1)

Now I’d like to plot “Output” over temperature, or, as a workaround, Output over time when the temperature goes from 0 to 90 °C in say 200 microseconds (which is really pointless in the reality but would exactly fit the simulation time of the other project, to see how the whole circuit works over time AND temperature).

The point would be to see the curve of “Output” over (linear) temperature.

Of course, I’d love to take both, temperature and resistance values from the plot …
