water heater water sensor

[Jay Darst]

While replumbing the new water heater, found a sensor that is 1/2"NPT
that has a single, very small wire that runs over to a relay which
powers the 120V to the water heater.

Appears to be a safety device so that the heating element is not ruined
when there is no water present.

The sensor I removed is severly corroded.

Can anyone point me in the direction of a replacement?

Thanks
