Cold 72F 8.42
hot 212F 107
super hot 300F 70

I would think super hot would have a higher value.
Let me know what you think.

Thanks,

John,

Can you re-clarify your readings please?

Your reading of 8.42, is this ohms or Kohms?

Typical temp senders are all NTC - negative temperature coefficient, meaning as temp increases, resistance decreases.

PTC is temp increase, resistance increase - just like any normal metal, steel, copper etc.
