Having looked over the previous oil temp sensor posts, I have to revisit the topic. Sorry.
I have suspiciously high oil temps on a Rotax 912 ULS, which is called out to use sensor setting #4. This setting yields a reading of 222 when tested in boiling water, which on test day was metered at 211.
The obvious troubleshooting showed that we have GOOD GROUNDS all the way round, and the high readings continue when the alternator is off.
If I set the sensor type to #2, it reads boiling water right at the correct 211 F. So . . . can I safely select sensor type #2 and have confidence it will read accurately at, say, 240-250, or is the curve going to change enough that it will read incorrectly at the higher temp?
For the record, I pulled all three Rotax-supplied thermistor-type temp sensors and boiled all three. There were 7 degrees F of variability between the highest and lowest readings with identical test conditions. I hate thermistors and really like J's and K's.
Have a safe and happy New Year and New Decade, folks.
Steve.
