Oil Temp Gauge Revisited, 200c temp sensor resistance vs temperature Options

[Superhawk996]

I think most people are familiar with the Panorama calibration graphics.



What I haven’t been able to find is the actual calibration curve for the 200C temp sensor that goes into the taco plate.

So . . . I went and got the data in an effort to help @ron914 troubleshoot is misbehaving oil temp gauge.

Oil was heated and a Fluke thermocouple meter was used to read oil temp. The resistance of the 200C sensor was measured both while heating and then on the cool down to get the hysteresis.

The pictures I’m going to attach later in this thread were done with a late oil temp gauge. The gauge I used pretty much matched the Panorama calibration graphics.

Here is the chart


Here is the raw data.
