Temp Sender

[dodj]

Does anybody have a chart or whatever that shows what resistance of the temp sender relates to what temperature? I have a gauge reading below quarter scale at running temps - tstat housing reading 195*. The temp sender register 182*. The sender reads 26.1 ohms.
Trying to determine if it is a gauge or sender problem.

My contribution towards temperature sending unit info.
Resistances at room temperature and in boiling water.
The first set is a spare I threw away, the second set is from my car

Thanks @Jay Bee   
So my sender is likely fine.  Just wire, gauge and regulator to investigate.
