Yes, the length of wire is of no consequence.

Heating up the sensor in water or vegetable oil would not make difference either.

But! you have to use a thermometer for the oil as it can go a lot higher than 212 degrees @ sea level.
At higher altitudes the water boils off at lower temperatures as it does not retain the heat.

I suggest testing that item and the engine coolant thermostats in oil for that reason.

I think it makes for a more stable reading from the bottom of the pan, there is no bubbles so you can see the plate first crack open, right on the degree and know when if its fully open or being lazy!
